Arthritis isn’t just 1 disease; it’s a complex disorder that comprises more than 100 distinct conditions and can affect people at any stage of life. Two of the most common forms are osteoarthritis and rheumatoid arthritis.
What is Arthritis?
Arthritis is an illness that can cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Some kinds of arthritis can cause problems in other organs, such as your eyes, or in your chest. It can affect your skin, too.
