Ive had a few lengthy discussions with my neurologist about this.
Im suffering severe leg and hand cramps at night after spending time in the heat, and have pain in so many areas.
He doubts its the MG. He says it doesnt take much to dehydrate in 85 degree temps if youre walking or moving around. and its been in the 80s or higher all summer long in the north east.
He tells me to double my fluid intake and maybe take in a sports drink instead of just water to supplement what is being wasted out.
