I once gave myself a neuropathy (nerve damage) while on a monthlong walking trip. The main cause was a combination of electrolyte imbalance and poorly fitting footwear that caused my feet to swell in my hiking boots and cut off circulation. Also, walking on those swollen feet for 15-25 miles daily for days on end... I think the constant pounding on hard surfaces may have also been a factor. By the time I got to the end, I couldn't feel 2-3 toes on each foot.

Nerves regrow at the rate of about 1/2" per month. It took a few months before I could feel all my toes again, all the way down to the tips.

Hopefully your situation is just temporary compression caused by swelling.
