Hi, Rachel. I'm sorry to hear that your husband more than likely has MS, but you sound like you have a great attitude, and that is very important. Family and friends who give support is extremely important to the one diagnosed. I know my husband has been wonderful since my dx last year. Thank God he is also brave enough to give me my injections every night, I am very fortunate. Anyway, your husband is going to be going through a lot of emotions now, and just being there for him will help tremendously.
MS isn't a death sentence, and your husband should go on with his life as normal as possible. I hope he plans on starting treatment ASAP, it's very important in slowing down the progression of the disease itself, and helps prevent flare-ups from happening as often. I started Copaxone a few months after my dx, and so far no problems.
Best of luck to you and your husband! Take care and God bless.
