i'm sorry you're suffering with so much pain.
sometimes when drs don't know they just pass you off instead of investigating and diagnosing. but MS is a tricky disease and finding answers is difficult.

i'd make an appt with your neuro. don't stop advocating for yourself. go in with your top 3 problems. when you're there in person the dr may offer more help.
try to take someone with you.

also, you might consider going to your pcp. sometimes they will come up with other solutions. i wonder if your pain is neuropathic. neurontin and lyrica can help with that. sometimes you can't help MS but only the symptoms it presents.

i hope you will feel better soon. let us know how you are.
