Shoulder Bursitis
Subacromial–subdeltoid bursitis
Understanding shoulder bursitis
A bursa is a small fluid-filled cushion that reduces friction as tissues glide. The one in the shoulder sits in the space under the tip of the shoulder blade — it's called the subacromial–subdeltoid bursa (one bursa, two names, because it spreads under both areas). When it gets irritated and inflamed, the shoulder aches and pinches, especially overhead. It's closely related to impingement and cuff irritation, and it settles well with calming the irritation and the strengthening this program is built around.
The reassuring outlook
Bursitis is not dangerous, and it responds well to a two-part approach: settle the inflammation, then strengthen the shoulder-blade and rotator-cuff muscles so the pinching that irritated the bursa stops happening. Most people improve steadily and get back to comfortable overhead use.
What your scans show — and don't
Imaging often reports "bursitis" or "fluid in the bursa." It's a common finding and frequently seen alongside the normal wear of a well-used shoulder. The finding alone doesn't dictate how you'll feel — the mechanics of how your shoulder moves matter more, which is what this program addresses.
What you might be feeling
Bursitis typically brings a pinch or ache reaching overhead or out to the side, tenderness over the top/outside of the shoulder, and discomfort lying on it at night. It usually eases as the inflammation settles and the supporting muscles strengthen. If anything new or unexpected comes up, or you're unsure how you're doing, your care team is the best place to check.
The plan: settle it, then strengthen
First, calm the irritation — gentle motion, easing off the overhead reaching that aggravates it, and ice or a short anti-inflammatory course if that's appropriate for you. Then build the shoulder-blade and rotator-cuff strength that opens up the space and stops the pinching, so the bursa isn't repeatedly irritated.
How this program is built
It starts gently — relaxed motion, posture, and shoulder-blade activation — while things settle, then builds shoulder-blade and cuff strength. Early on, favor movements below the painful arc; you'll reclaim overhead range as the irritation calms and the mechanics improve.
Staying comfortable day to day
While it's irritable, ease up on repetitive or sustained overhead reaching, keep good posture, and use ice after activity if it's sore. As it calms, gradually return to your normal use. Keep the arm gently moving rather than resting it stiff.
When it flares
When it's more bothersome: keep moving gently below the painful arc, ease off overhead reaching for a few days, use ice, and a short anti-inflammatory course if appropriate for you. Then ease back in. Flares settle and don't undo your progress.
Tracking how you're doing
Your quick daily check-in gives you and your care team a shared view of how things are trending — a simple way to see progress and keep your care team in the loop. It is not a monitoring or warning system.
