question: I had awoken to a small red itchy bump on my arm , figured it was a flea bite and caulked it off. The next day I had 2 in the same area. Scratching them caused a 3rd to show up. They have white heads are sore yet itchy. Since then a 4th has appeared so I covered them with clear nail polish so I wouldn t scratch them. Now on day 5 I have a red rash 1 inch in diameter around one of them that is raised.
