Arthritis is a term used to describe more than 100 different types of joint inflammation. Arthritis causes stiffness, soreness and swelling where two bones meet, such as the shoulder, elbow, hip and knee. The most common types of arthritis are osteoarthritis, rheumatoid arthritis, lupus and gout.
Arthritis symptoms usually include:
With osteoarthritis, you may hear clicking and crackling sounds when you bend a joint, such as in your hip or knee. Additional symptoms may include fever, fatigue, muscle aches, eye pain and skin redness.
Arthritis can be caused by a number of factors, depending on the type.
The main cause of osteoarthritis is wear and tear of cartilage and bone. Cartilage is smooth, flexible tissue that cushions the ends of bones and helps them move freely.
As autoimmune diseases, rheumatoid arthritis and lupus cause your immune system to mistake healthy tissue as harmful to your body and attack them, leading to inflammation of the joints. In RA, your body makes antibodies against the lining of your joints. With lupus, your immune system attacks your joints, as well as other parts of the body.
Gout is caused by a buildup of uric acid crystals in your joints. This condition is most common in men over 40 and can be brought on by a diet rich in foods and beverages containing high levels of purines like game meats, shellfish and alcohol.
Your doctor may use these methods to diagnose arthritis and determine which type of arthritis you have:
Although there is no cure for arthritis, certain medications may ease your joint pain and reduce inflammation, while physical and occupational therapy can help maintain the flexibility of your joints. Keeping your weight down, exercising regularly, and applying cold and warm compresses to trouble spots can also provide relief.
