Itchy bite sort of marks on my stomach and back?

i have these 3 blemishes on my stomach. one is nearish my boob below it, and on is on my side and the last one is near the side one on my back. they seem like theyre bites, kind of like mosquito bites but swollen like that. its clear that theyre bites. at first when i noticed something was iritating me on my stomach, it felt like the feeling you get when ur feverish and when you touch your skin it sort of hurts. i dno how else to describe it. and yeah thats how it startedout, so i didnt think i had a bite at all. but then it developed into that, so what do you guys think it could be?
