- Top of the race is flat and not rounded up when you look at the page.
- A slight pain when I pushed, and only when it is pressed.
- Rosenrot
- A slightly dry skin at first, but not hot
- No extension (until now)
- Has been put on the thumb for 2 ½ weeks and has not changed the way in the past week and a half.

What is it? I do not think this is a wart. I had a wart before, and it does not look like it. But not all warts are the same so I could be wrong. It could be herpes? I have no idea!

I waited to go on them, so I have not seen a doctor. My friends say that they do not Look as a wart, but do not touch on the event that spread.
