Hi, at one time I was on 150 mg at night & 25 mg in the mornings of Endep, it doesn't do anything in the repairing process but it used to help calm down the burning pretty well.
In my case the numbness took the longest to heal, even when the burning had stopped completely, the numbness took many months later to heal; it healed in a patchy fashion then eventually healed completely.
Sounds like your doing all the right things so hopefully in time yours will heal in a similar manor.

best of luck to you
