5 Days ago I spent the night at a hotel. When I woke up in the morning I had a red bump on the side of my stomach. I figured it was a bug bite, it was the size of a dime and a little sore. Now its 3 inches wide, still red and swollen. It is still sore, and it is right where my pants sit on my waist. It feels like their is somehting (puss) maybe inside. No white center or dot in the middle though!!! I dont want to do to the doc's if they are just going to give me a topical medication! any ideas??
