Shoulder pain can range from mild to severe and can come on suddenly or build up over time. Shoulder pain causes include fractures, tissue inflammation or tears, joint or ligament instability, and arthritis. It can also stem from conditions that don’t directly involve the shoulder at all.
Treatment for shoulder pain will vary depending on the specific condition. Treatment options may include rest, medication, and physical therapy. In some serious cases, surgery may be recommended.
