How long for strength to return?
After my first 5 day loading dose I had an immediate improvement. Unfortunately it was short lived and did not maintain itself on what I call my 5 months of under treatment.
Since that time I would describe any improvement as taking place over months. Not weeks, months. In my case, due to the severity of nerve damage in some places, no improvement is expected in those places.
time, give it time. Lots of time.
