A shoulder injection is an image-guided procedure that places medication directly into the shoulder joint, the subacromial bursa, or around the rotator cuff to reduce pain and inflammation. Dr. Imran Qureshi performs three types: corticosteroid (cortisone) for fast inflammation control, hyaluronic acid for shoulder arthritis lubrication, and platelet-rich plasma (PRP) as a regenerative option for tendinopathy and partial rotator cuff tears. Most cortisone injections take 5–10 minutes, provide relief within a few days, and last weeks to months. The injection is performed under ultrasound or fluoroscopic guidance for accuracy at the Katy, TX office.
What is a shoulder injection?
A shoulder injection delivers medication directly to the structure causing your pain — most often the glenohumeral joint (the main shoulder joint), the subacromial bursa (a fluid-filled sac above the rotator cuff), or the soft tissue around an inflamed tendon. Compared to oral medications, an injection produces a higher local concentration with much less systemic effect, which is why a properly placed shoulder injection often relieves pain that pills could not touch.
Dr. Qureshi uses image guidance — typically ultrasound, sometimes fluoroscopy — on shoulder injections. Image-guided shoulder injections are significantly more accurate than blind ("landmark-only") injections, especially for the subacromial bursa and small joints, which directly improves both pain relief and safety.
What conditions does a shoulder injection treat?
Dr. Qureshi commonly recommends a shoulder injection for:
- Rotator cuff impingement and tendinopathy — pain when reaching overhead, sleeping on the shoulder, or lifting
- Subacromial bursitis — inflammation of the bursa above the rotator cuff causing aching, sharp pain with motion
- Shoulder arthritis (glenohumeral osteoarthritis) — chronic stiffness and aching that worsens with activity
- Frozen shoulder (adhesive capsulitis) — progressive loss of motion, often paired with sleep-disrupting pain
- Partial rotator cuff tears — particularly for PRP, which may stimulate healing rather than just mask pain
- Biceps tendonitis and tenosynovitis — pain at the front of the shoulder
- AC (acromioclavicular) joint arthritis — top-of-shoulder pain, often after years of overhead lifting or athletics
- Sports injuries with persistent shoulder pain — see our sports injuries overview
If you are not sure where your shoulder pain is coming from, Dr. Qureshi will examine the shoulder and review imaging before deciding whether — and which kind of — injection makes sense.
What types of shoulder injections does Dr. Qureshi offer?
Three options, each with different strengths:
- Corticosteroid (cortisone) — the workhorse for acute or flaring inflammation. Fast-acting, covered by insurance, and provides weeks to several months of relief for bursitis, impingement, and arthritis flares. Limited to 3–4 per shoulder per year.
- Hyaluronic acid (viscosupplementation) — restores joint lubrication for shoulder osteoarthritis. Typically given as a series of 1–3 injections over a few weeks. A good option when cortisone is no longer giving meaningful or lasting relief, or when steroid use is contraindicated (poorly controlled diabetes, for example).
- Platelet-rich plasma (PRP) — uses the patient's own concentrated platelets to stimulate healing in tendinopathy or partial rotator cuff tears. Regenerative rather than purely anti-inflammatory. Typically self-pay; Dr. Qureshi will discuss whether your specific shoulder is a good PRP candidate.
What happens during a shoulder injection?
The procedure is short, well-tolerated, and performed in the office:
- Positioning: You sit upright or lie comfortably with the shoulder exposed.
- Skin prep and numbing: The injection site is cleaned and numbed with local anesthetic.
- Image guidance: Dr. Qureshi uses ultrasound (or fluoroscopy when appropriate) to visualize the target — joint space, bursa, or specific tendon — and confirms the needle is exactly where it needs to be.
- Medication delivery: The injection takes under a minute. You may feel pressure or a brief stretch sensation as the medication is placed.
- Walk out: Unlike spinal injections, no monitored recovery is required. Most patients drive themselves home.
Why image guidance matters for shoulder injections
Studies consistently show that blind shoulder injections miss the intended target — particularly the subacromial bursa and the glenohumeral joint — at rates of 30% or more. An injection that misses the inflamed structure does not deliver the relief the patient came for. Using ultrasound or fluoroscopy to confirm needle position before any medication is given is the simplest way to make sure the injection actually does what it is supposed to do. Dr. Qureshi makes image guidance a standard part of every shoulder injection.
Recovery and timeline
- First 24 hours: Avoid heavy lifting, overhead motion, and impact activity. Ice 15 minutes, 2–3 times. Some patients have brief soreness from the needle itself.
- Days 1–3: Cortisone may not be working yet — and a small percentage of patients have a steroid flare with briefly increased pain. This passes.
- Days 3–7: Cortisone effect kicks in. Most patients notice meaningful pain reduction by day 5.
- Days 7–14: Full benefit. This is the right window to ramp up rotator cuff strengthening and physical therapy.
- Beyond 2 weeks: Relief commonly lasts weeks to several months. Hyaluronic acid effects build over the series; PRP results unfold over 6–12 weeks as healing progresses.
Am I a candidate for a shoulder injection?
You may be a good candidate if you have:
- Persistent shoulder pain that has not fully responded to 4–6 weeks of physical therapy and over-the-counter anti-inflammatories
- Pain that limits your sleep, work, or sports
- An imaging or exam finding that points to a specific structure (bursa, joint, tendon) Dr. Qureshi can target
- A desire to avoid or delay shoulder surgery
Cortisone injections are not recommended in the setting of active joint infection, uncontrolled diabetes, severe full-thickness rotator cuff tears with planned surgery, or documented allergy to the components. PRP is generally avoided in patients with active blood disorders, anticoagulation, or recent cancer treatment. Dr. Qureshi will review your medical history before any injection.
What are the risks and side effects of a shoulder injection?
Shoulder injections under image guidance are very safe. Possible side effects:
- Temporary pain flare: 1–2 days of increased soreness, especially with cortisone
- Temporary blood sugar elevation: Diabetic patients should monitor for 48–72 hours after a steroid injection
- Skin pigment lightening or fat-pad thinning at the injection site: Uncommon, related to repeated steroid use in the same area
- Allergic reaction to the medication: Very rare
- Infection: Very rare with proper sterile technique
- Cartilage and tendon effects: Why we limit cortisone to 3–4 per shoulder per year
Shoulder injection vs. surgery: which makes sense first?
For most shoulder problems short of a complete rotator cuff tear with significant weakness, a well-targeted injection plus structured physical therapy is the right first step. Many patients who think they need surgery actually do well long-term after one or two image-guided injections combined with rehab. Surgery is reserved for cases where conservative care fails, structural damage is significant, or function does not return. Dr. Qureshi will tell you honestly when an injection is not enough and a surgical referral is the right call.
