Bug Bite Like Bumps Popping Up On Skin What Kind Of Bug Bite Is This?

What kind of bug bite is this? - bug bite like bumps popping up on skin

Okay, so in my right breast, near the tip of a sting have recently revealed that I do not know when or how I do. But it hurts. Could a spider bite? And if so, what kind of spider. Or something for my little brother?
There is a time that does not hurt. At the beginning it was just a bruise or even injured. Then, in about a day that started badly and the next day when I saw it swells up like an ant bite, with the white kitten in, and then, without knowing what it was I took, and there was a amount of pus. Moreover, it is now red and Irita around them, and the skin around it is hard and it hurts like hell. Also my right arm started badly, and I know that class is no gym, there's nothing more embarrassing at all. Here's a picture of a small number iss on my dick, and if you shot after a boob, they will not get, which is really just the bite.
In any case, please give your opinion?
And do not say that this went to the doctor, my mother, embarking on one.
And please take seriously?
Thank you.
