Contrary to popular belief, arthritis is not just one disease. It is actually a complex disorder, comprising more than a hundred different conditions. It can affect any person at any stage of his life, whether he is generally healthy or suffering from some other form of degenerative disorder.
The most common forms of this disorder are osteoarthritis and rheumatoid arthritis, each having very different causes, risk factors, and effects on the body, but the same common symptom: persistent pain in the joints.
