Ok WOMEN ONLY!?

Sometimes I would try to not wear a bra and do things and if you over do it(like I did), that could pull or hurt muscles that your breasts are holding up. May want to create sure you wear a bra, even if you feel similar to you would not want to!

I want to detox so I can gain more energy and lose a few extra pounds?

Could be too much Caffeine.
Seriously.

Or you could freshly be premenstrual

Does having sex too much rationale..?

Thats kind of a touchy subject. Im not a doctor but when my boobs hurt its because my period on its way.

Girl Stuff?

I construe it is of age. If you are still in puberty you might purely be a growing pain. But if you are not next it must be a knot contained by your muscle. I recommened massaging it.
