I have had three bumps show up in the last two days underneath my clothes. I thought they might be spider bites, but they didn't look like it up close so I figured they were mosquito bites. But they still didn't act like they were. I have two on my inner thigh, three on my stomach, and one on my chest just under my breast that I just found today. I'm not sure what's going on, and I'm trying to find answers. They are no bigger than a penny right now, itch like crazy, and when I touch them there's a weird burning and sharp itchy pain. Sometimes I don't even have to touch them and they start burning and itching. Any ideas on what this is?
