I also got MS from Enbrel, and I also have no family history of MS. The Enbrel worked great for the AS, but I started feeling dizzy all the time, and then I fell a couple of times for no reason. I still have some problems from the MS. I was on Avonex for several years. I think the decision should be between you and your doctor. If you do go on it keep a close eye out for signs of MS. I had about 6 months before I started feeling dizzy.
