Joint pain is a common problem that can be caused by a wide variety of conditions. The knee, hip, shoulder, and ankle are some of the most commonly affected joints, but joint pain can also affect other joints in the body. Joint pain is often the result of inflammation, which can be caused by injuries, infections, or autoimmune diseases. In some cases, joint pain may also be caused by arthritis or other degenerative conditions. Treatment for joint pain will vary depending on the underlying cause. In many cases, over-the-counter pain medications and physical therapy can help to relieve symptoms. However, severe joint pain may require more aggressive treatment, such as corticosteroid injections or surgery.
