I am one of them. I've been on Enbrel several years with no serious side effects
and complete relief from RA flare-ups. There's a good chance it'll work for you too, but you won't know unless you try. Every patient is as different as a fingerprint.
Having said that, it is ALWAYS your choice, your body! If you're determined to try the natural route, don't rely on the internet for information. Go see a certified naturopath.
Exercise is never a bad idea.
