Shoulder bursitis improves with a combination of rest, ice, anti-inflammatory medication, and targeted exercises. Most cases resolve within a few weeks using these conservative measures, and only a small percentage of people ever need injections or surgery. The key is reducing inflammation first, then gradually rebuilding strength and mobility so the problem doesn’t come back.
What’s Happening Inside Your Shoulder
Your shoulder contains a small, fluid-filled sac called a bursa that sits in the narrow space between the top of your arm bone and the bony shelf of your shoulder blade. Its job is to cushion the rotator cuff tendons so they can glide smoothly when you raise your arm. When that space narrows, whether from repetitive overhead movements, poor posture, or age-related changes, the bursa gets pinched and inflamed. That’s bursitis.
Several factors can trigger or worsen this narrowing. Forward-rounded shoulders (common from desk work) change how the shoulder blade moves, pushing structures into the bursa’s space. Tightness in the back of the shoulder capsule can force the arm bone to shift upward during movement. Even the shape of your acromion (the bony roof above the bursa) can make some people more prone to impingement than others. Understanding these mechanics matters because effective treatment addresses the underlying cause, not just the pain.
First Steps: Rest and Ice
Stop any activity that triggers pain. This doesn’t mean immobilizing your shoulder completely, which can lead to stiffness and make things worse. It means avoiding the specific movements that hurt, particularly reaching overhead, lifting heavy objects, or sleeping on the affected side. Switch to activities that keep the shoulder moving gently without stress.
Apply ice or a cold pack for 10 to 20 minutes at a time, with a thin cloth between the ice and your skin to prevent frostbite. Do this several times a day during the first week or two, especially after any activity that aggravates the shoulder. Ice constricts blood vessels in the area, which helps reduce swelling inside the bursa.
Over-the-Counter Pain Relief
Ibuprofen and naproxen are the most commonly recommended options because they reduce both pain and inflammation. These are typically used for a few weeks while the shoulder heals. If your pain persists beyond a month, continued use should be monitored by a doctor, since long-term NSAID use can cause stomach and kidney problems. Acetaminophen can help with pain but won’t address the inflammation driving the bursitis.
Exercises That Help Recovery
Once the acute pain starts settling (usually after a few days to a week of rest and ice), gentle stretching and strengthening exercises become the most important part of treatment. These fall into two categories: stretches to restore range of motion and strengthening moves to stabilize the shoulder and prevent recurrence.
Stretches for Mobility
Each stretch should be held for 15 to 30 seconds and repeated 2 to 4 times. Start gently and never push into sharp pain.
- Posterior shoulder stretch: Bring the affected arm across your chest at shoulder height, using your opposite hand to pull it closer. You’ll feel a stretch along the back of your shoulder.
- Up-the-back stretch: Reach the affected arm behind your back as if tucking in a shirt, then gently guide it upward with your other hand or a towel.
- Supported shoulder extensor stretch: Stand at a table or counter, place both hands on the surface, and slowly lean forward until you feel a stretch through the front and top of your shoulders.
- Lying rotation stretch: Lie on your back holding a stick or cane in both hands. Use your good arm to gently rotate the affected arm outward, keeping the elbow at your side.
Strengthening Exercises
These are typically done for 8 to 12 repetitions. Isometric exercises (where you push against resistance without moving) are a good starting point because they build strength without stressing the joint.
- Shoulder-blade squeezes: Sit or stand with good posture, squeeze your shoulder blades together, hold for 6 seconds, and relax. This trains the muscles that keep your shoulder blade in the right position during movement.
- Isometric flexion and extension: Stand facing a wall and press your fist into it (for flexion) or stand with your back to the wall and press backward (for extension). Hold each push for 6 seconds without moving the joint.
- Wall push-ups: Stand at arm’s length from a wall, place your palms flat, and perform slow push-ups. This activates the shoulder stabilizers with minimal load.
- Resisted rotation: Using a resistance band anchored at elbow height, rotate your forearm inward and outward while keeping your elbow pinned to your side. These target the rotator cuff muscles that control the position of your arm bone within the joint.
Progress gradually. If an exercise causes more than mild discomfort, scale it back or wait a few more days before trying again.
How to Sleep With Shoulder Bursitis
Night pain is one of the most frustrating parts of shoulder bursitis, and poor sleep positions can slow your recovery. Sleeping on your back is the best option. Place a pillow under the affected arm with your elbow bent and your hand resting across your stomach. This lifts the arm slightly and takes pressure off the bursa.
If you can’t fall asleep on your back, lie on your unaffected side and stack two pillows in front of your chest, resting the affected arm on top. This keeps the shoulder in a neutral position. Sleeping on the affected side is the worst option, but if you tend to roll that way, place a flat pillow under your waist and leave a gap between it and your head pillow, creating a channel for your shoulder so it isn’t compressed against the mattress. Avoid sleeping on your stomach entirely, as this forces the shoulder into an impinged position.
Workstation Adjustments
If you work at a desk, your setup may be contributing to the problem. When your keyboard or mouse is positioned so your elbows have nowhere to rest, the muscles around your shoulder fatigue and pull the joint forward into a rounded posture. Over time, this posture narrows the subacromial space and keeps the bursa irritated.
Set your monitor at arm’s length with the top of the screen at eye level. Your elbows should be bent at roughly 90 degrees with your hands at elbow height on the keyboard. Make sure there’s enough desk space in front of you to rest your forearms comfortably. If your chair has armrests, adjust them so your shoulders can relax downward rather than hiking up or reaching forward.
When Injections Make Sense
If several weeks of home treatment and exercises haven’t provided enough relief, a corticosteroid injection into the bursa is often the next step. The injection delivers a powerful anti-inflammatory directly to the source of swelling. If the injection includes a numbing agent, you’ll feel relief within minutes, though that wears off after a couple of hours. The steroid itself takes a few days to kick in as it reduces the swelling.
Pain relief from a single injection can last several months to up to a year. Not everyone gets the same duration of benefit, and injections are generally limited to a few per year because repeated steroid use can weaken surrounding tendons. An injection works best when combined with physical therapy, so you’re fixing the mechanical problem while the steroid buys you a pain-free window to do the exercises.
Surgery as a Last Resort
Surgery is reserved for cases that don’t respond to months of conservative treatment. The most common procedure is arthroscopic subacromial decompression, where a surgeon shaves away a small amount of bone from the underside of the acromion to create more room for the bursa and tendons. The inflamed bursa itself may also be removed, as the body generates a new one over time.
Studies report successful outcomes in 75% to 85% of patients who undergo this procedure for impingement. Recovery involves a period of restricted activity followed by a progressive physical therapy program, and most people see meaningful improvement over a few months. It’s a reliable option when conservative treatment has been given a fair chance and hasn’t worked, but the vast majority of people with shoulder bursitis never reach this point.
