Subacromial bursitis is a common cause of intense pain in your shoulder that gets worse when you move. Getting treatment early can help prevent long-term joint problems.
Your shoulder is another common place for bursitis. The subacromial bursa in each shoulder helps a group of muscles and tendons known as the rotator cuff to function. If it gets swollen, you have subacromial bursitis.
Sometimes, an injury damages the bursa in your shoulder. Overuse of your shoulder muscle can also cause damage. People who do a lot of overhead lifting and forceful pulling on the job are at risk.
Being very active can also harm your bursa, especially if the sport you play involves throwing or pitching.
Other factors that can cause this type of bursitis:
- Your age. Bursitis in your shoulder becomes more likely the older you get.
- Poor posture. Sit up straight, don’t slump.
- Poor flexibility. Stretch before you work out.
The shape of your shoulder bone can be a factor too. You may have less space between your tendon and bursa than most people. An infection, arthritis, gout, diabetes, or thyroid disease can also play a role.
