Doddle I think that the nerves are always trying to regenerate and re grow
but I am not a doctor or anything. The nerves may not "re-grow" but the may be trying to and that may be what is causing the t.n. pain
I have no idea how or why just think that nerves even tho they may be severed or damaged... nerves are always trying to re generate .
I hope you are able to get rid of the new pain. a.d. is enough !!
Sending my prayers and healing thoughts to you .

PEACE
