definitely see a doc. even tho your only 14, you can still get breast cancer. especially if it runs in the family.
there are many factors why the breast sometimes hurts.
1. your menstrual period is going near.
2.muscle pain
3,there's a cease/lump on it.
observe yourself and if it is really annoying try to consult an expert most probably if you fel some lumps on it, because it can be sometimes cancerous.
thanks but now i have another problem...i have a lump type thing there now...it hurts when i touch it.
yeah its pretty normal at your age. your chest is still growing and will continue to grow for a LONG time. This is probably just your breasts developing. dont be surprised if just when the left one stops hurting, the right one starts. oh and also, its completely normal to have one breast smaller than the other, and dont ever let anyone tell you different :o)
It's possible it's related to your development. When you're first getting to your full size, the breasts can feel hard, and then sore.
oh and im 14...so is this normal...?
