i'm sorry too for what you're going thru. it's not easy to deal with things like that.

i'd talk to your dr. good advice. maybe a change in med would help.
do you have an MS specialist in your area? maybe a 2nd opinion in the MS area would give you some other answers.
to you poochie.. hope you feel better. don't give up searching for answers. it doesn't matter what kind of MS it. just treat the symptoms.
