I tried Fampyra too, I had good results leg wise whilst I took it. I stopped because of side effects I couldn’t cope with.
My walking continued to be very good for about three months then took a sudden nose dive and was far worse than pre fampyra…this continued for ages and I really though it was going to stay that way however, very very slowly it has returned to how it was originally.
Hopefully the same will happen for you Tina, given a little more time. By the way I took LDN at the same time as fampyra… my MS nurse knew this and didn’t ask me to stop, possibly because LDN helps amazingly with my bladder and bowels but has never helped my walking that I know of.
There is a theory that LDN could possibly slow progression, if that’s true maybe it has helped me but it certainly hasn’t slowed progression for me in other areas.
Hope things improve for you Tina,
