My number was at 119 and started supplements plus monthly shots. I am remembering about six or five shots and the numbers went to over 900. My strength got better but I don't know if any nerves healed. I guess that they had to be some healing otherwise how did strength improve? I don't know if the muscles that have good nerves got stronger or did nerves heal to create more signals to involve more muscle fibers. There may be tests that could shed light on this chicken or egg type question but after so many tests I got to where I didn't care as long as improvement was happening. Good Luck, Ken in Texas.
