What is a Rheumatologist?

A rheumatologist is a physician who is qualified by additional training and experience in the diagnosis and treatment of arthritis and other diseases of the joints, muscles and bones. Many rheumatologists conduct research to determine the cause and better treatments for these disabling and sometimes fatal diseases.

Rheumatologists treat arthritis, certain autoimmune diseases, musculoskeletal pain disorders and osteoporosis. There are more than 100 types of these diseases, including rheumatoid arthritis, osteoarthritis, gout, lupus, back pain, osteoporosis, fibromyalgia and tendonitis. Some of these are very serious diseases that can be difficult to diagnose and treat.
