Any advice out there on frost bite or frost nip? Apparently the doctor has said it's more like frost nip... what's the difference? I'm asking for my son who's away at the moment. Army medics don't seem overly worried about it but it's bothering him. Loss of feeling generally in both big toes which returns in the form of tingling occasionally (especially when he's at home and warm) and then disappears. Been going on quite a few months now. Will it disappear over a period of time? Anything he can do to help it? If this has been covered elsewhere, my apologies and please point me to the thread.
