hello and welcome to NT.
dej always says things so well. her advice is sound.

IF you do have MS getting a dx (diagnosis) is a process of elimination so it may take some time to have tests done.
i went to my PCP when my gait problems started. her exam came up abnormal so she sent me to a neuro and the rest was hx.

try to take one thing at a time and one day at a time.
when you look at just what's in front of you it's not as scary. and worrying doesn't help anyway.

i agree with getting disability thru work. make sure you have good health insurance. don't carry this burden alone. consider sharing with your husband.
it the tables were turned what would you want him to do?

let us know how you are.
