In reply to Brucemacrosson:
I am still recovering from a grade 2 frostbite I got on the tips of my toes about 8 weeks ago. The dead tissue has turned to small scabs now but still have some swelling, so they're not fully back to normal. The advice I have gotten from doctors who specialise in cold injury and plastic surgery was to protect the tips and keep them warm since the capillaries will still be very delicate and you don't want to do further damage while they're healing. Ibuprofen and aloe vera were also recommended on a daily basis, mainly to keep inflammation down and to aid healing of the damaged tissue. Might be worth getting professional advice/consultation if uncertain?!

I'd find some alternative activities to keep you entertained while you're fingers are healing (running, biking, cross country skiing - things that don't use the fingers too much??). It'll take some weeks but in the long term will probably be worth it!
