It is amazing how many of us on this board either have MS or knows a loved one or friend that has it. Heat and humidity are the most common factors and I live in Florida so go figure! But I keep my body relaxed when I can and well hydrated. As for insurance its true. When I started my shots 8 yrs ago they cost $1,590 now they are $4350 a month! I do have health insurance but I also contacted the maker of the shots and they have an assistance program that has helped me for the last yr. and a half. I highly suggest that anyone can call these manufacturers and they will assist you. I too was am still am afraid once they cut me off the assistance then what? I'm divorced and live alone and its a scary feeling that someday I will wake up and not be able to use my legs at normal function (right now my left leg is giving me problems).
