How do I get rid of mosquito bites?

I went to a bonfire 4 days ago and only wore shorts. After 2 days, I noticed I had a ton of red spots on my legs. I counted 28 red spots about the size of the back of a tack. I noticed there were some mosquitos around me that night, but the weird thing is they haven't really been itchy. I don't know what else it can be. They look horrible though, and it has been 4 days and they are still really red! I have scratched them a little, but I mean really hardly at all. I'm glad that they don't itch, but isn't it a little weird that they don't, and especially since I didn't realize that I even had them til 2 days later? I haven't done anything outdoorsy since that night. That is the only way I know that I got them. Any ideas on what these could be, and how I can make them go away?
