I had it too.(and it's over now, now I have it on my other toe. fuuuu-)
You gotta put your foot with the hurting toe in a big bowl of warm water and soda, and then leave it like that for about 10 minutes. Then you gotta try to push your toe a bit, and there might be some yucky stuff coming out of it.
But if you want to do it the easy way: Visit your nearest doctor.
