These terms are often used interchangeably to describe conditions involving stiff, swollen and inflamed joints. Arthritis is only one of the many forms of the much larger category called rheumatic diseases, all of which share similar symptoms . Depending on the type of arthritis you have, tissues other than the joints may be affected, including muscles, blood vessels and lungs. The exact causes of the rheumatic diseases are unknown, but treatments are available to relieve pain and prevent their crippling effects. If you experience pain, swelling, or stiffness in the joints, seek medical advice without delay.
Early treatment is most successful.
