I have these red bumps primarily on my lower legs 2 on each arm, and one on my back. First, about 4 days ago, I got 5 ish, and I believe that they were normal mosquito bites since I'd been outside. The marks are still there but vague. Then this morning I woke up and realized I had gained about 16 total more "mosquito bites", decided to wear pants and boots to school, and when I got home and changed to shorts, realized I had gained another 12 "mosquito bites".
