Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder that causes the immune system to attack the joints, where it causes inflammation (arthritis) and destruction. RA can also attack the skin, lungs, kidneys, and your heart.
It can be a painful condition that can lead to loss of functioning and mobility. To diagnose RA, blood tests and X-rays can determine if someone has it or not.
Various treatmenst are available where you can treat and suppress the symptoms.
