Breast bumps.?
Answers: It sounds approaching it could be an ingrown hair, or other sort of skin infection. Is at hand a free clinic in your nouns?
How big is the pimple? Is it really red or hot to the touch? If it is infected, which it sounds like it might be, you may require some antibiotics, depending on how severe it is. You can try putting a thaw out compress on it to ease the soreness.
If by the side of the crease of your breast, you be determined closer to your armpit, then you may want to research the skin disease hidradenitis suppurativa. It sounds a bit like that to me. Unfortunately, here is no good treatment. There are surgical option, but they are almost worse than the condition itself. I think what you enjoy is a pustule it is not life threating or anything.They can be cause because of the pressure of your underwire or bra which in that nouns makes sense.Try wearing a losser bra or giving your self time to rest next to out a bra for a while.I would pop it and not put pressure on it to let it restore to health. I had them to and i know it hurts to pop but for me if i pop it within the shower it did not hurt as much.
