Bug bites all over my body!?

I used to have ants in my room(My room's next to the balcony door) and ever since then I would wake up with these bumps on my wrists, lately it's spread to my hand, arms, and legs. They itch sometimes and it's starting to scare me. They weren't fire ants since I never felt a burning sensation, I've checked my room and I've driven out/vacuumed all the ants. My room is on the second floor of our house and I had to tape the bottom of the balcony door to try and keep the ants out. The bites are really starting to scare me, what should I do?
