I have been on just about every pain med known to humanity, most were useless and had some really nasty side-effects. The last one I was on was Topamax, which sort of worked but left me mentally in an Alzheimers condition! My family doctor guggested cannabis (yes, marijuana): did that ever work well!! I am now on Sativex (a cannabis extract, not synthetic) and it works, too. It is approved in Canada especially for MS.

Things will get better, I hope.
