Joints Pain – Types & Causes
In osteoarthritis (OA), the protective cartilage inside the joint breaks down. This makes movement of affected joints more difficult and painful. In time, bones of the joint may rub directly against one another, causing severe pain. Pain can also come from parts of your joint other than the cartilage, such as bone, synovium and ligaments.
In rheumatoid arthritis (RA), the joints and other organs are attacked by the body’s own immune system. The immune system normally protects a person from viruses, bacteria and other invaders. In people with autoimmune diseases like RA, it becomes overactive and attacks healthy tissue.
Psoriatic arthritis (PsA) is an autoimmune inflammatory disease in which the immune system attacks the body, causing inflammation and pain. PsA affects the joints, causing arthritis; the connective tissue where tendons or ligaments attach to bones, causing enthesitis; and the skin, causing psoriasis.
Gout is a form of inflammatory arthritis, but it does not cause body-wide inflammation like RA or PsA does. In gout, uric acid crystals are the problem. If your body produces too much uric acid or if you are unable to remove the excess fast enough, it can build up in the blood (called hyperuricemia). Excess uric acid can form crystals in your joints.
Lupus is an autoimmune inflammatory disease that affects many parts of the body, including the joints, kidneys, skin, blood, brain and other organs. It can cause joint pain, fatigue, hair loss, sensitivity to light, fever, rash and kidney problems.
Back pain can be a symptom of several forms of arthritis and related conditions, including ankylosing spondylitis, psoriatic arthritis and fibromyalgia. Most back pain, however, is the result of some type of injury, such lifting or bending improperly, a sports injury or an automobile accident.
