I was diagnosed 21yrs ago and Iam having my first relapse..I'm having tightness and pins and needles on leftside of my body..what is the best med to take for muscle spasms? I'm suppose to go on a cruise with my kids first time ever in 2weeks feb 2nd and need to get better quick. I have a new neurologist that is not able to accept me in until after I'm supposed to return from the cruise....I'm really stressing about this😔😔...is flying a big concern for new lesions? Is it not a great idea to continue with my trip?
