I used to get them all the time, knock on wood, I haven't gotten one for a long time now. My grandmother used to give me this stuff to put on them, and it would like rinse all of the white part of them out. It would burn like hell but it killed all the white part of them and left a red crater, which hurt but it hurt less and healed quickly. I forgot what it was called though sorry. Does the magical mary jane help with the pain?
