RA is an inflammatory process because your own immune system attacks your own cells, which is considered an autoimmune disorder. This can weaken your joints and in time deteriote bones and cartilage within your joints. Some common symptoms of RA include: fatigue, morning stiffness, muscle aches, loss of appitite and weakness, and joint pain. Othere symptoms, which are not as common, include: redness, swelling, round nodules on joints and skin, deformities, and a low grade fever.
Treatment include: Disease modifying antirheumatic drugs (DMARDs): These drugs are the current standard of care for RA, in addition to rest, strengthening exercises, and anti-inflammatory drugs. Methotrexate (Rheumatrex) is the most commonly used DMARD for rheumatoid arthritis.

Physical Therapy can aid in pain relief and prevention by using range-of-motion exercises and individualized exercise programs prescribed by a physical therapist can delay the loss of joint function. Joint protection techniques, heat and cold treatments, and splints or orthotic devices to support and align joints may be very helpful.

If you suspect you have RA, take the Rheumatoid Arthritis Screening Quiz found in the following link: http://arthritis.about.com/od/rheumatoidarthritis/l/blrheumarthquiz.htm
It is a good idea to seek your personal physician for blood specific tests (Rheumatoid Factor) to be specifically diagnosed as well as seeking the aid of a rheumatologist.
