Seara...I would gladly smack the crapon peas out of her for you!! I might understand the no diagnosis but being rude and insensitive...oh no, not to one of my babies!!

You forget about her and try to find a neurologist that is a MS specialist, not one that just treats MS. Take the MRI and results to another if she can't give you an answer.
I had a neuro tell me it wasn't MS after being treated for over three years...you don't need the meds he said...stop taking them...I did and went on a hospital vacation for 12 days!!
You don't have to 'suck it up', you need answers as to why you feel as you do. Migraines are usually caused by something...I've had them for over 30 years...so don't just discard those headaches. It seems that you could get the sx treated for some relief even if not a diagnosis.
I am sooo sorry your appointment did not go well and hopefully you can get answers...what state are you located. Someone here might know a very human neurologist! I found as a rule most neuros are not 'people' oriented, I've been very lucky to have two that are and several other docs also.
Sending you more...

Smack, smack...lets all smack this neuro...she wasn't in Savannah was she...sounds like one I did a follow up with. lol
