Welcome to the MS club....sorry, but at least you know what you're fighting.
Copaxone is helpful to some in cutting back on the MS attacks but not on most...it didn't stop my progression. My advise try it and see?? Working is okie dokie.
I don't recommend steroids, they only help to possibly shorten your attack, but can be harmful to your body in large/prolonged use. The only thing is you don't know if it worked until, sometimes, weeks after you stop taking it. In the meantime, nervousness, sleeplessness and agrivation are side effects. Working? Up to you?
Neither one is a cure, so It's your choice, if the Copax isn't working, stop it!!!
I hope Copaxone works for you and you are feeling better soon.
