Dermatitis of Normal Variation (also called, "NOS") means that all of those other causes of your rash have been ruled out. This is very common.

    Rheumatoid arthritis (RA) is a form of arthritis that causes pain, swelling, stiffness and loss of function in your joints. It can affect any joint but is common in the wrist and fingers. RA is an autoimmune disorder, meaning that it is caused by the immune system incorrectly attacking the joints when it shouldn't.

    You should visit your primary care physician who will coordinate care with a specialist. RA is a complex disease, which can require prescription medication to help slow down the damage to your joints, as well as pain killers such as ibuprofen (Advil), or naproxen (Anaprox and Naprosyn). Exercise, especially swimming, can also help with pain and stiffness.
