dear skywalker,

i wish i could address your sx's but i don't have enuf knowledge about it.
i think it's a great idea to get another opinion and see another dr.
never stay with a dr if they don't listen and validate you, or you're not getting the help you need. especially if you're dealing with a serious illness like MS.

i hope you see this new dr soon.

you can always use the ER as a backup if needed. not ideal but the option is there. stay in contact with your pcp too for help. let us know how you are.
