i agree wholeheartedly with the others.
look for another neuro. preferably an MS neurologist.
it's difficult for them to dx with a clear mri but you still need someone who will listen, validate and tx you like an adult.

i would also look for a good internist to be your pcp (primary care physician).
if you can, bring a friend or family member to your dr visit. sometimes that can make a dr listen better.

some of us get told it can't be MS because we're too old. age doesn't have anything to do with it. sx's are incidious. they're different for every person.
you know your own body best.

it is a good idea to keep a sx journal with dates you have certain symptoms.
the timeline can help the dr with a hx (history).

you are your own best advocate. keep looking and don't give up.
you might also call your local MS society at 1-800-FIGHT MS. ask for a list of drs that you could see. it might be a start. or, you might try a dr in a university setting.

welcome to NT. i hope you get some answers. please keep in touch with us.
