Copaxone takes at least 6 months to begin showing a positive effect (slowing progression is the ideal). As others have mentioned it's not a cure, and it won't work for every person on it.

With that said, if you've tried the other options and it's a last shot, I'd still give it a chance if your budget allows. Or get a second opinion maybe?

I still feel that 6 months on Copaxone is not enough time to be looking to MRIs to see if it's working or not. I'm very sorry regardless to hear that your MRIs were showing a lot of progression, and that your doctor called you with someone else's info That alone would freak me out and question his or her integrity.
