Dear Bulee,
Acute Rheumatic Arthritis - In simple term is an autoimmune disease, where auto - antibodies are formed for self destruction. Normally the joints,eye,skin etc are the organs commonly involved for the same.
I agree that there is no prefect cure for this.But we have got medicines, which and control it. They are called as DMARD (Disease Modifying Anti Rheumatoid Drugs).
So its better to consult a Rheumatologist, who can perform various test/examination to arrive at a proper drug dosage.
As per your post it appeared that you are bit too worrier about this disease.But please understand that this is a controllable disease.Just need to see a right doctor.
Regards
