Shoulder subacromial bursitis is usually best treated with non operative management during the first few months. often, the pain can be reduced considerably, and function can be improved. Often an operation is not required. The following is a list of things that should be attempted before contemplating surgery.

1. Physiotherapy is very important is reducing the symptoms of subacromial bursitis. When the bursa is inflamed, the small muscles (rotator cuff muscles) of the shoulder are deactivated, and this worsens the condition. The rotator cuff muscles act to hold the ball and socket in the correct alignment, which reduces pressure on the bursa. Physiotherapy can, on its own, reduce the symptoms of bursitis.
2. Anti-inflammatory medication – Taken in short spurts, this can be a safe and effective method to reduce pain. Anti-inflammatory medication can interact with other medications, so ensure that you check with your doctor first. You should only take this sort of medication on a short burst regimen. A few days on and then a few days off
3. Steroid injections into the shoulder are useful, and can be performed with or without ultrasound guidance. Local anaesthetic and steroid are injected into the bursa, causing the burial inflammation to decrease. An injection on its own will not cure bursitis as physiotherapy is required to maintain the effects of the injection, if it is to be long lasting.
4. Avoidance of overhead and aggravating activities.
