Shoulder pain can be caused by numerous factors, such as overuse, injuries, arthritis, or underlying medical conditions. It may also result from poor posture or muscle imbalances. Treatment options for shoulder pain include rest, ice or heat therapy, over-the-counter pain medication, physical therapy, and in some cases, cortisone injections or surgery. Strengthening and stretching exercises can also help alleviate shoulder pain. It is important to seek medical advice to accurately diagnose the cause of shoulder pain and develop an effective treatment plan tailored to individual needs.
