It's especially nifty for the drug companies that whenever a patient complains that the DMD wasn't doing any good, they can say, "Ah, but you have no idea how much worse your MS would be if you hadn't been taking that DMD!"
I've told my neuro that I'll be willing to go back on Copaxone if the MRI next December shows that the MS has worsened considerably since going off it (May 2010).
But when I said that I'd forgotten about the left groin pain attacks I used to have while on Copaxone. They were really crippling. I'm very glad to be rid of them.
Not to mention the bowel urgency problem, which was getting severe. Or the permanent lipoatrophy dents.
