Im sorry you have lost faith and trust in your MD. that stinks!
Take a list with you. Write down everything you want to ask, and refuse to leave till you ask them. Put the most important ones first.
Is this MS? Why do you think it is or isnt MS? If not MS, what is it?
What medicine will they reccomend for you. not just the injectable stuff, but also the muscle relaxers, or anit anxiety or other such stuff. Will they be willing to be the ones to give you meds to help control this, or will they count on your regular MD to do that?
I am sure these good folks are going to come up with loads of good suggestions. you came to the right place.
