I hit my toenail pretty hard and it's radiating heat?

I had something like this last summer. Firstly, do NOT panic. Toenails grow back. You have a 50-50 chance of keeping your toenail on if you, secondly, do not touch it unless you are applying disinfectant ( try rubbing alchohol, it'll sting like hell, but it works really well, trust me!!) or changing the bandaids. You must change the bandaids every so often or else do not use them at all, or you'll only keep the infection where it is. Good luck and may a happy, non- infected toe come back to you soon! :)
