You are right that this pain is more of the neurological then of bony origin. This type of pain is called causalgia. It can be treated by neurologist
. i have following suggestions to my patients.
1. Tablet Pregabalin
and Methylcobal for nerve healing.
2. Nerve block
can be tried, it is given by pain specialist anesthetist.
3. it may be possibility that your nerve is getting entrapped in scar tissue of the surgery, so neurolysis can be done, in this procedure, nerve is explored surgically, freed from scar tissue and then fixed with underline tissue.
