Keri, sorry to hear about the flare.
If you've been on copax for more than 6 months, your neuro may be right that it's not the DMD for you. As to the HiCy, I'm not sure what it's time table might be. I know they usually say wait for the 4th infusion for Ty, but don't know about the other.
Hope whatever comes next will help you out. Hang in there.
