I messed with it a little bit, and the next day it had swollen up
and was warm, like an infection. Since then, I have been using Abreva
and Differin on it. The Differin makes the largest difference – it reduces the size significantly.
When it first showed up, it looked a lot like this picture: http://www.adamjbc.f2s.com/dlc/test/Photo-0171.jpg. It no longer has a white tip, and there are two small bumps (neither red nor painful) below it.
