Ouchies! Sorry you severed some nerves.

Nerves can take quite awhile to mend, months and even a year or so in some cases. It can cause tingling and pain while in the process.

I'm not sure what exactly can be done to make the process less painful or less tingly. Vitamin B may help with the regeneration process, but I think it's important to speak with your dr about this. Hopefully you won't require surgery to the nerves and they will repair themselves.

Wishing you well!
