Causes include injury, abnormal metabolism (such as gout), inheritance (such as in osteoarthritis), infections (such as in the arthritis of Lyme disease), and an overactive immune system (such as rheumatoid arthritis [RA] and systemic lupus erythematosus). Symptoms of arthritis include pain and limited joint function. Treatment may include pain medications, pain-relieving creams, and dietary supplements.
Knee Pain Knee pain has a wide variety of causes and treatments. Home care for knee pain involves protecting the knee from further trauma, in addition to resting, icing, compressing, and elevating the knee. In order to diagnose knee pain, the physician may need to perform a physical exam, get an X-ray, CT scan, MRI, remove fluid, and/or perform blood tests or arthroscopy. Treatment of knee pain depends upon the cause of the knee pain.
