As far as spasms go for me, Ampyra sure didn't reduce them. They're still terrible. Forgot to take my morning Baclofen 40mg (120 per day) and holy bleep. I took them throughout the day and were still bad even when I went to bed.

Sensory is still going downhill.

Strength is there but I have to hand it to testosterone (80-100mg week) & daily exercises including swimming.

I can't recommend Ampyra as of now over cheap testosterone. Everyone's MS is different though so try it..maybe?
If something improves strength by jumpering nerves, why doesn't it improve sensory??? I don't understand this one.
