Signs and symptoms of joint pain
Joint pain can be classified as either mechanical (activity related) or inflammatory. Osteoarthritis — the most common cause of mechanical joint pain — is the inherent repair process of synovial joints and not a disease, as commonly thought. Sometimes this process fails and patients present with symptoms of pain and functional impairment. Joint pain classification is based on signs and symptoms; X-rays are not needed.
