For Rheumatoid Arthritis Rheumatoid arthritis since 1994, pretty severe case. Had to stop taking Humira and methotrexate due to repeated bouts with pneumonia and lung damage. Currently on sulfasalazine, Plaquenil and prednisone. Occasional flares but things are basically back under control.

For Rheumatoid Arthritis I have been on these meds for 6 weeks now. Started with one pill a day, then increased weekly to four pills a day. It has greatly helped with my pain. I'm sleeping better at night and especially within the last week, have been able to go about life almost how I did prediagnosis. So for that part - I would recommend giving it a go. As for side effects, I've been fortunate enough to not experience any type of stomach upset or headaches or anything like that. I have however been losing alot of hair. I can run my hand through very lightly, no tugging whatsoever, and end up with about 20 strands. I can run my hand through continually like this and the same thing happens. No pain from pulling, just falling out :( Choosing to tough it out for now
