Gabapentin is great for long term nerve pain, but I can’t imagine a doctor prescribing gabapentin for something as short term as wound healing - at least not in the UK. Heat, distraction, OTC antihistamines and maybe a prescription for something like zopiclone for short term relief if the itching is preventing sleep completely, should provide enough relief from the itchiness.
OP, I’m not sure if you can stand at the moment, but be extra careful when standing up if the loss of feeling extends to your foot. I have neuropathy and dislocated my ankle just getting up off the sofa before it was diagnosed. It definitely takes some getting used to and taking more care over how you step. Get well soon!
You didn’t say whether you were talking about the nerve pain or the itching mentioned in the title, so I was clarifying.
