this hurts for a moment, but usually fixes it on most people.

soak toe in warm salt water. soak some cotton in alcohol. take tiny balls of cotton and stuff them under the nail and put bandaid lightly over.

in 24 hours, take out, drain, and replace with slightly bigger dry balls of cotton. like 1/16" then 1/8".

Keep doing for 3 days. If worse, go to doctor. If better, http://en.memgenerator.pl/mem-image/you-re-welcome-en-ffffff
