We went camping on despite buy spray I got ate alive by mosquitos which is what I thought this was when I first say it. I just assumed I had scratched it to much and it swelled. but here we are over a week later all my mosquito bites are healed and this hasn't even started to shrink. It's about the size of a quater and slightly raised not much. it also doesn't have a definitive hard spot like a big bite. Any ideas? Should I do worried?
