It is important to have an evaluation to determine which arthritic disease is causing the problem. Like other illnesses, early diagnosis and treatment of arthritis can impact the outcome of the illness.

The diagnosis of a particular kind of arthritis usually depends on a lot of different information. If someone with joint problems sees a rheumatologist, a medical doctor specializing in the diagnosis and treatment of arthritis, the evaluation will begin with a history of the problem: When did the symptoms start? Which joints hurt? Are the joints stiff? What makes the symptoms worse or makes them feel better? A physical exam of the joints, x-rays, and certain lab tests will also typically be done. It is important to know that the symptoms of some types of arthritis develops over time and may appear similar to other types in the early stages. It may take several visits before the doctor can tell what type of arthritis a patient has.

If joint symptoms occur and persist, it is important to determine which specific arthritic disease is causing the problem. Like other diseases, the earlier the diagnosis is made, the better the outcome is likely to be. Another reason to have an accurate diagnosis is that different arthritic diseases require different treatments. Most arthritic diseases are not curable, but most are manageable and respond to treatment, often requiring some combination of medication (pills or infusion), joint injection, physical therapy, and surgery.
