hi thanks for posting Mycroplasma has no role to play in the above said condition.Rheuatoid 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. 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. The usual drug given in rheumatoid arthritis are methotrexate,sulfsalazine and HCQS. My advice would be visit a rheumatologist/physician for evaluation and treatment. Hope this information suffices. Take care
