Hi Tom, in my experience, small positives seem to happen very slowly, hardly noticeable at that time, but over a period all those little positives really do add up.
If you are looking back now thinking i couldn't do this a few months back without very noticeable weakness, but can do it now, then that does sound very promising to me.
Nerve healing is very slow, but not impossible, 3 years back i wouldn't have dreamed that i could be sitting at this computor without any very irritating burning in my feet and up my legs, but i fortunate enough to say i am.
good luck, i hope it is all positive signs for you.

Brian
