Subacromial bursitis occurs when the small fluid-filled bursa at the top of the shoulder becomes irritated or inflamed. This bursa helps reduce friction when lifting or rotating the arm, so when it becomes inflamed, everyday movements, especially reaching, typing or raising the arm, can feel uncomfortable.
At work, certain postures and repetitive tasks can quietly increase irritation in the bursa. Understanding these patterns makes it easier to reduce strain and maintain better shoulder comfort throughout the day.
When the bursa is inflamed, positions that compress the space around the shoulder can make symptoms more noticeable.
Common workplace patterns include:
• Working with the arm held away from the body
Reaching forward for the mouse or typing without forearm support increases compression under the acromion.
• Elevated or “hunched” shoulders
A desk that’s too high, or sitting too low in the chair, often causes the shoulders to lift — narrowing the space around the bursa.
• Repetitive reaching or side movements
Using a distant mouse, rotating repeatedly towards a side monitor or reaching for items across the desk can irritate the area.
• Staying in one position too long
Stillness increases stiffness around the shoulder and makes the bursa more reactive when moving again.
These patterns can combine to increase irritation and prolong recovery.
Subacromial bursitis often responds well to reduced compression, better arm support and gentle, comfortable movement.
1. Keep the arm close and supported
Bring the keyboard and mouse nearer so the elbow stays close to the body.
Use the desk surface or an armrest to lightly support the forearm and reduce load on the shoulder.
2. Adjust desk and chair height
Aim for a setup where the shoulders can rest comfortably without lifting.
If the desk is high, raising the chair and adding a footrest can help the shoulders relax.#3. Use soft, pain-free mobility
3. Use soft, pain-free mobility
Gentle movements help maintain comfort without aggravating the bursa. Helpful options include:
All movements should feel easy and non-provocative.
4. Break up long periods of stillness
Every 20–30 minutes, shift your posture, stand for a moment or change arm position.
These small resets help prevent the shoulder becoming stiff or “catchy.”
5. Avoid positions that compress the shoulder
For comfort, try to limit:
These changes reduce irritation and help settle symptoms over time.
Subacromial bursitis can make everyday desk tasks surprisingly uncomfortable, but small adjustments often lead to meaningful improvements. Supporting the arm, reducing overhead or forward reaching and using gentle, comfortable mobility can ease irritation and promote smoother recovery during the working day.
