Hi
Thanks for posting your queryRheumatoid arthritis  is a disease that is autoimmune in nature. It affects mainly synovial joints like the joints of hands, feet, although any joint can be affected by it. Just like various chronic diseases like diabetes, 
hypertension  and ischaemic 
heart disease are not curable but controllable; rheumatoid arthritis is also controllable. 
With proper medication you can lead an absolutely normal life without any pain or 
disability. The drugs usually given are 
methotrexate ,HCQS,Sulfsalazine along with 
folic acid  and pain killer.
It is not advisable to stop medication on your own as it only leads to accrual of joint damage and leads to joint deformities. So keep a positive attitude and take regular medication; also exercise regularly. 
Please feel free to ask me if you have any other query. Do you have a family history of multiple joint pains?
My advice would be visit a rheumatologist/physician for evaluation and treatment.
Hope this information suffices.
Take care
