Ah, the left hand giveth, and the right hand taketh away! welcome to the medical world of MS.
If you get 10 MS MDs in the same room at the same time, talking about the same patient, you will probably get 10 differing diagnosis, AND 10 different treatment plans.
Your best bet is to find a neuro/ms MD who you like, trust, and can believe in, and stick with him/her.
I hope you are able to get everyone on the same page, the rest of us have been trying to do that too.
