If you suspect you may have arthritis in your shoulder, it's important to consult with a healthcare professional for an accurate diagnosis. Common symptoms of shoulder arthritis include persistent pain in the shoulder joint, tenderness, stiffness, decreased range of motion, and a clicking or grinding sensation during movement. An evaluation by a medical expert, such as a rheumatologist or orthopaedic specialist, may involve physical examinations, imaging tests (such as X-rays or MRI scans), and a review of your medical history.
