Welcome-this is a great place for info, laughs, and hugs.
I was dxd with fibro in 85...fibro mimics lots of MS sxs. I was told by my orthopaedist in 2000 to watch out for MS...he and his collegues were seeing lots of fibro patients go into MS.
Personally I believe that Fibro is a precurser to MS...they never did MRIs of my brain when I had fibro, so who's to know if I already had lesions?
Keep getting informed, so that when you go to a doc you have a well-informed list of questions for him/her.
good luck! I took me over 3 years after first seeing a neuro before I got a dx. Don't give up. If you feel that you're right, keep on fighting!
