In Feb 08 I began taking Copaxone for MS. Shortly after I began using Copaxone, the right side of my tongue went numb. I initially stopped taking the Copaxone to see if it would resolve itself. It didn't and I continued with the Copaxone. The right side of my tongue is still numb, the numbness on the right side of my mouth has resolved mostly but now I have the most horribly dry mouth. I have tried everything--even so much as sucking on a mouth full of vinegar. I can get my mouth to water with salty or sour foods, but it doesn't stay moist. I have tried what I think is everything over the counter to help but nothing is working! What can it be and What can I do? It is making me insane! Please help!
