Is there any cure for rheumatoid athritis?

No cure, but. Remission is obtainable for most patients with RA with are current drugs!
RHEUMATOID. while there is no "cure" in the last 10 years there have been HUGE, REALLY REALLY HUGE benefits to patients with the use of immunosuppressive and biologic drugs and other new treatments so if you have RA get under the care of a rheumatologist right away as the drugs are disease game changers despite the side effects and risks.
See a rheumatologist. Rheumatologist can give you the best advice and treatment plan for ra.
