Hi Kvan, Welcome to the site. It is so hard to say whether nerve damage from injury can be permanent. I wish I could tell you exactly when or if the numbness will subside, but I can't. Does it cause pain in your toe or numbness? If it is painful there are things you can take for it. Mrs. D would be able to help you with the natural remedies. Look at some of the stickies and see if there is anything there that may be helpful.

As for the friend, not sure I can give any advice on that. Not sure what the circumstances are and don't want to give advice that may not be the correct thing to do.

Good luck with everything. Let us know how you make out.
Hopeful
