Really glad to read the good news, Barb...
I've been reading about people's experience on Ampyra on the NMSS site on Facebook...almost everyone has seen improvement in their foot drop as well as tingling/numbness lessening, cognition improvement and vision improvement. My neuro said he saw all of these in patients in clinical trials through him.
So maybe you'll see improvement, too. by the way, the drug company is helping patients defray the costs...my neuro had me fill out a form that is sent to the drug company (at least I think that's where it went). It then goes to a coordinator who works with the insurance company to figure out how much they'll chip in...at least that's what I've been told.
Don't give up on trying this drug...
