Shoulder impingement syndrome is a common cause of shoulder pain. It happens when the tendons and soft tissues in your shoulder get irritated or pinched, especially with frequent overhead movements like swimming, tennis, volleyball or even lifting objects.
Repetitive motions can cause these tissues to rub against nearby bones, leading to discomfort and inflammation. It can also happen after a minor injury, like falling on your shoulder or reaching out to catch yourself. Sometimes, the exact cause isn’t clear.
If shoulder impingement isn’t treated, the pain can get worse and make it hard to move your arm or do daily activities. Early treatment can help relieve discomfort, reduce inflammation and restore shoulder function.
