Hi guys, I had a meeting with my neroligist last week in which I told her I am getting the odd numbness/symptoms from my MS. I've been on Demethyl Fumarate (Tecfidera) gor 10 years now. She has said this is expected after being on a medication for do long, my nervous system is kind of starting to reject it. Although the symptoms come they font stay for you long, possibly 15 minutes maximum, if I were to tone it. Any suggestions on which F.T would best fit when I desperately need to change???
