Joint, Bursa & Trigger Point Injections

Villanueva Institute of Pain and Spine

Joint, Bursa, and Trigger Point Injections in Burbank, CA

Joint, bursa, and trigger point injections can reduce pain from inflammation, irritation, arthritis, bursitis, muscle knots, and certain tendon-related conditions. When pain in the shoulder, knee, hip, elbow, wrist, sacroiliac joint, tailbone area, or muscles makes it harder to move through the day, a focused injection may help calm the painful area and make normal activity more manageable.

I am Dr. John Villanueva, double board-certified in PM&R and interventional pain management at the Villanueva Institute of Pain and Spine (VIPS). I perform joint, bursa, and trigger point injections for patients whose pain is affecting movement, sleep, work, exercise, driving, sitting, walking, or the everyday routines they want to get back to. A future without pain is possible, and it’s my goal to help you achieve it.

These injections are not all the same; a painful knee joint is different from an irritated bursa, and a trigger point in the muscle is different from trigger finger. Before recommending a procedure, I review your symptoms, exam findings, imaging (if needed), prior treatments, and how pain is affecting your life. That helps us choose a treatment that fits the problem instead of guessing.

If you are looking for joint, bursa, or trigger-point injections in Burbank, CA, call VIPS at (818) 669-8895 or request an appointment online. We are located in Burbank and proudly serve patients visiting from Glendale, Pasadena, Van Nuys, Toluca Lake, Studio City, Sherman Oaks, North Hollywood, Sun Valley, La Cañada, La Crescenta, Los Feliz, Atwater Village, Silver Lake, Echo Park, and communities throughout the San Fernando Valley and greater Los Angeles area.

What Are Joint, Bursa, and Trigger Point Injections?

Joint, bursa, and trigger-point injections are focused treatments that deliver medicine directly into or near a painful structure. Depending on the condition, the injection may include a local anesthetic, anti-inflammatory medication, or another appropriate treatment.

  • Joint injections place medication into a painful joint, such as the shoulder, knee, hip, elbow, wrist, or sacroiliac joint. They may be considered when arthritis, inflammation, injury, or joint irritation is causing pain.
  • Bursa injections target an inflamed bursa. A bursa is a small fluid-filled cushion that helps reduce friction between bones, tendons, and soft tissues. Bursitis can cause pain with walking, sitting, lying on one side, or using the affected area.
  • Trigger point injections target tight, painful bands of muscle that can cause local pain or referred pain. These injections may be considered when muscle knots are not improving enough with stretching, physical therapy, massage, medication, or activity changes.


The appropriate treatment depends on where the pain is coming from. Hip pain, for example, may come from the hip joint, the greater trochanteric bursa, the ischial bursa, the sacroiliac joint, the lumbar spine, or muscles around the pelvis. A careful evaluation helps narrow that down.

What Areas Can These Injections Treat?

Joint, bursa, and trigger point injections may be considered for several painful areas, including:

  • Shoulder
  • Knee
  • Hip
  • Elbow
  • Wrist
  • Sacroiliac joint
  • Sacrococcyx or tailbone region
  • Ischial bursa
  • Greater trochanteric bursa
  • Trigger finger
  • Painful muscle knots in the neck, back, shoulders, hips, or extremities


The location of pain is only part of the story. I also want to understand what the pain feels like, what movements bring it on, what has helped before, and whether symptoms suggest a joint, bursa, tendon, nerve, spine, or muscle source.

Joint Injections

Joint injections are often useful when pain appears to stem from inflammation or irritation inside a joint. This may include arthritis, overuse, prior injury, mechanical irritation, or inflammation that makes movement difficult.

At VIPS, I may consider joint injections for areas such as the shoulder, knee, hip, elbow, wrist, sacroiliac joint, and other painful joints when the diagnosis supports it. Some patients feel pain mainly with movement. Others notice stiffness, swelling, clicking, difficulty walking, pain with overhead motion, or pain getting in and out of a chair or car.

A joint injection may provide relief, but it can also give useful information. If numbing medication improves your usual pain, it may help confirm that the joint is a meaningful pain source.

Bursa Injections

Bursa injections are used to treat bursitis, a condition in which a bursa becomes irritated or inflamed. Bursae help cushion the soft tissues around joints, but when they become inflamed, they can make common movements difficult.

At VIPS, bursa injections may be considered for conditions such as greater trochanteric bursitis, ischial bursitis, shoulder bursitis, elbow bursitis, or other painful bursa-related patterns.

Greater trochanteric bursa pain is commonly felt on the outside of the hip and may make it difficult to lie on that side, walk for longer periods, climb stairs, or stand comfortably. Ischial bursa pain is usually felt near the sitting bone and may become more noticeable with prolonged sitting.

The injection has to match the suspected pain source. Not all hip or buttock pain is bursitis, which is why I take time to consider the hip joint, sacroiliac joint, low back, nerves, tendons, and surrounding muscles as well.

Trigger Point Injections

Trigger point injections are used to treat painful muscle knots or tight bands of muscle. These trigger points can cause pain in the muscle itself, but they can also refer pain to nearby areas.

Trigger points may occur in the neck, upper back, shoulders, lower back, hips, gluteal muscles, or other muscle groups. Some patients describe an intense ache, tightness, burning, pressure, or a pain pattern that seems to spread from one area into another.

A trigger point injection may include local anesthetic and, when appropriate, other medication. The purpose is to relax the painful muscle area, reduce irritation, and help you participate more comfortably in stretching, posture work, physical therapy, or other parts of your treatment plan.

Trigger Finger Injections

Trigger finger occurs when one finger or thumb catches, locks, clicks, or becomes painful with bending and straightening. This often happens because the tendon is not gliding smoothly through its sheath.

A trigger finger injection places anti-inflammatory medication near the affected tendon sheath at the base of the finger or thumb. For some patients, this can reduce inflammation enough to improve pain, catching, and hand function.

Trigger finger is different from joint arthritis or a muscle trigger point. During your evaluation, I will review where the pain occurs, whether the finger locks or catches, how long symptoms have been present, and whether other hand or wrist conditions may be involved.

Sacroiliac Joint and Sacrococcyx Injections

The sacroiliac joint sits where the spine meets the pelvis. When the sacroiliac joint is irritated, pain may be felt in the low back, buttock, hip, groin, or upper thigh. It may worsen with standing, walking, stairs, rolling in bed, or getting in and out of a car.

A sacroiliac joint injection may help reduce inflammation and also let us know whether the sacroiliac joint is adding to your pain. Because the SI joint can overlap with lumbar spine, hip, and pelvic pain patterns, diagnosis matters.

Sacrococcyx injections may be considered for certain patients with tailbone pain, also called coccydynia. Tailbone pain can make sitting, rising from a chair, driving, or leaning backward very uncomfortable. The best approach depends on your symptoms, exam findings, imaging when needed, and prior response to care.

Good Candidates for Joint, Bursa, and Trigger Point Injections

You may be a good candidate for joint, bursa, or trigger point injections if your symptoms, physical exam, and history suggest that a specific joint, bursa, tendon sheath, or muscle area is causing pain.

Suitable candidates may have:

  • Shoulder, knee, hip, elbow, or wrist pain that limits movement
  • Sacroiliac joint pain affecting the low back, buttock, hip, or pelvis
  • Tailbone pain that worsens with sitting or pressure
  • Greater trochanteric bursa pain on the outside of the hip
  • Ischial bursa pain near the sitting bone
  • Trigger finger with catching, locking, or pain at the base of the finger
  • Painful muscle knots that have not improved enough with conservative care
  • Pain that interferes with sleep, work, driving, walking, exercise, or daily routines


These injections may be considered when medication, rest, physical therapy, stretching, activity changes, or prior treatments have not provided enough relief. They may also be used when pain is making it difficult to participate in rehabilitation.

How I Evaluate You Before Recommending an Injection

Before recommending a joint, bursa, or trigger point injection, I want to understand what structure is most likely causing the pain. Two patients may both say they have hip pain, but one may have hip joint arthritis, another may have greater trochanteric bursitis, another may have sacroiliac joint pain, and another may have pain coming from the lumbar spine.

During consultations, I routinely review:

  • Where your pain starts and where it travels
  • Which movements, positions, or activities make it worse
  • Whether you have stiffness, swelling, weakness, catching, locking, numbness, or tingling
  • Prior imaging, procedure notes, medications, therapy, or surgical history
  • Whether pain is limiting sleep, walking, sitting, work, exercise, driving, or family life
  • Whether X-rays, MRI, ultrasound, EMG/NCS testing, or referral to another specialist may be needed


Some patients have one clear pain source. Others have several overlapping issues. A shoulder can have joint pain, bursitis, tendon irritation, and neck-related nerve pain at the same time. The evaluation helps decide where to begin.

Why Choose VIPS for Joint, Bursa, and Trigger Point Injections?

Injection care should be specific, thoughtful, and connected to how pain is affecting your life. At VIPS, I do not treat these injections as routine shots. I use them when the history, exam, and imaging support the diagnosis.

When you choose VIPS, you can expect:

I am double board-certified in PM&R and interventional pain management. My PM&R training helps me understand joints, muscles, nerves, movement, function, and rehabilitation, while my interventional training allows me to perform targeted procedures when they are appropriate. As a double-board-certified physician and Certified Life Care Planner, I bring additional specialized training in evaluating the long-term needs of individuals with complex injuries and disabilities. This includes assessing future medical care, rehabilitation, and other ongoing needs that may be relevant in a medical-legal setting.

I review your symptoms, exam findings, prior care, imaging when needed, and daily limitations before recommending a joint, bursa, trigger point, sacroiliac, sacrococcyx, or trigger finger injection.

Some injections are best performed with ultrasound or fluoroscopy to help guide placement. I choose the approach based on the target area, your anatomy, and what is safest and most clinically appropriate.

Pain in one area can come from another source. Hip pain may come from the hip joint, bursa, SI joint, spine, tendons, or muscles. I take time to connect those pieces instead of assuming the most obvious location is always the cause.

If an injection makes sense, I will explain why. If physical therapy, medication management, imaging, EMG/NCS testing, regenerative medicine, spine treatment, or a surgical opinion is more appropriate, I will tell you directly.

Relief matters, but so does what relief allows you to do. I want to know whether pain is keeping you from lifting your child, walking comfortably, sleeping through the night, exercising, working, sitting through a drive, or living without constantly guarding the painful area.

Many patients come to VIPS after feeling dismissed, rushed, or unsure what to try next. My team and I want you to be acknowledged, informed, and comfortable asking questions before any treatment is performed.

What Happens During Joint, Bursa, or Trigger Point Injection Treatment?

For a joint injection, the treatment area is cleaned, and medication is placed into or near the affected joint. Depending on the joint and the clinical situation, I may use image guidance to help confirm accurate placement.

  • For a bursa injection, medication is placed near the inflamed bursa. This may be done for areas such as the greater trochanteric bursa, ischial bursa, shoulder bursa, or elbow bursa when the symptoms and exam support the diagnosis.
  • For a trigger point injection, I identify the painful muscle area and place medication into the trigger point. You may feel pressure, a twitch, or brief soreness during the injection.
  • For trigger finger, the injection is placed near the irritated tendon sheath at the base of the affected finger or thumb. The visit is usually straightforward, and I will explain what to expect before we begin.

What Should You Expect After the Injection?

Your response depends on the area treated, the medication used, the diagnosis, and how your body responds. Some patients feel improvement soon after the injection, especially if a local anesthetic is used. Anti-inflammatory medication may take longer to have its full effect.

You may have mild soreness, pressure, bruising, or temporary discomfort near the injection site. I will review what is expected, what activities to modify, and when to contact the office.

Your response also helps guide the next step. If the injection helps, that may support the suspected diagnosis and make it easier to participate in physical therapy, stretching, strengthening, or activity progression. If relief is limited, we may need to reconsider the pain source or discuss another option.

How Long Do Joint, Bursa, and Trigger Point Injection Results Last?

The duration of relief varies. Some patients notice short-term improvement, while others have relief that lasts weeks or months. Results depend on the diagnosis, treatment area, medication used, activity level, underlying condition, and whether the pain is part of a larger pattern.

A knee injection for arthritis, a bursa injection for lateral hip pain, a trigger point injection for muscle pain, and a trigger finger injection all have different expectations. I will explain what is realistic for your specific condition.

For many patients, the most meaningful benefit is being able to move more comfortably, sleep with less interruption, walk farther, sit longer, use the affected arm or hand more easily, or return to routines with less constant attention to pain.

Joint, Bursa, and Trigger Point Injections and Your Broader Treatment Plan

Injections often work best as part of a larger plan. Depending on your condition, your care may include physical therapy, rehabilitation planning, medication management, activity modification, bracing, imaging, EMG/NCS testing, regenerative medicine, or cooperation with another specialist.

If pain is coming from a joint or bursa, a targeted injection may be useful. If the pain is coming from a tendon tear, an unstable joint, an irritated spinal nerve, an inflammatory condition, or a surgical problem, another approach may make more sense.

At VIPS, we take time to review your symptoms, exam findings, history, prior treatment response, and daily limitations. Pain care should help you spend less time protecting the painful area and more time using your body with comfort and confidence.

Burbank Joint, Bursa, and Trigger Point Injection FAQs

If joint pain, bursitis, muscle knots, sacroiliac pain, tailbone pain, or trigger finger is making your days harder to move through, a focused injection may help clarify the next step in your care.

To schedule a consultation for joint, bursa, or trigger point injections in Burbank, CA, call (818) 669-8895 or contact VIPS online today. The right care may help you spend less time working around pain and more time moving through life with comfort, confidence, and peace of mind.

Some are, depending on the target area. At VIPS, ultrasound or fluoroscopy may be used when image guidance improves accuracy or safety. Small or deeper structures, such as the hip joint, sacroiliac joint, or certain bursa targets, may benefit from image-guided placement.

Some patients feel temporary relief soon after the injection because of local anesthetic. Anti-inflammatory medication may take longer to work, and improvement may develop over several days. I will explain what to track after treatment so we can interpret your response.

If an injection does not provide meaningful relief, that information is still useful. It may mean the pain is coming from another structure, that imaging or nerve testing is needed, or that another treatment should be considered. I will review your reaction and discuss the next appropriate step.

The cost of joint, bursa, or trigger point injections in Burbank can vary depending on the treatment area, whether image guidance is used, the procedure setting, and your insurance benefits. During your consultation, my team can help you understand what information may be needed for scheduling, authorization, and cost review.

A cortisone shot is one type of joint injection. Many joint and bursa injections use corticosteroid medication to help calm inflammation, but the exact medication depends on the diagnosis, treatment area, medical history, and reason for the injection.

The number of injections depends on the joint, diagnosis, medication used, response to treatment, and overall care plan. I do not want injections to become automatic. If repeated injections are being considered, I will talk with you about whether they still make sense or whether another treatment should be explored.

Many patients can drive after a minor injection, but this depends on the treatment area, medication used, and how you feel afterward. If an injection may affect your ability to drive safely, my team will let you know ahead of time so you can plan for transportation.

After an injection, you may be asked to avoid strenuous activity involving the treated area for a short period of time. Most patients can return to light daily activities, but I will give you specific instructions based on the injection performed, your diagnosis, and your usual activity level.

Yes, bursa injections may help when bursitis is causing pain in areas such as the outside of the hip, shoulder, elbow, or near the sitting bone. The important step is confirming that the bursa is truly the pain source, since hip and shoulder pain can also come from joints, tendons, muscles, nerves, or the spine.

Trigger point injections may help painful muscle knots that have not improved enough with stretching, physical therapy, massage, medication, or activity changes. These injections are often used as part of a larger plan to reduce muscle irritation and help you move more comfortably.

A joint injection treats pain coming from inside or around a joint, such as the shoulder, knee, hip, wrist, elbow, or sacroiliac joint. A trigger point injection treats a painful muscle knot or tight band of muscle. The right injection depends on whether the pain is coming from the joint, muscle, bursa, tendon, nerve, or another structure.

Sometimes, injections may help reduce pain and improve function without surgery when a nonsurgical plan is appropriate. However, injections are not a replacement for surgery when surgery is indeed needed. If your exam or imaging suggests that a surgical opinion makes more sense, I will tell you directly.
