When I was 26 I started feeling a menthol taste..it took two days but one morning my toung and lips went numb..by the end of the week I was completely numb on my right side...from the tops of my head (I had some deafness) down to my big flippin toe.

I was dxed with RRMS and have been on treatment since. I also suspect I have Celiac as well. Have you had MRIs?
