Constant Heaviness In The Chest

   I don't know why, but if you stop smoking, it will be easier for you to breathe.

   Hello :) I understand your anxiety, I also went through something similar, I want to tell you that you are still a growing organism and your body develops first, it is normal for your breasts to hurt. Personally, both of them really hurt me a lot (although I never smoked), but I can advise you to consult your mother or if you are very worried go to the doctor :) But remember that at this age it is normal to encounter chest pain-they grow like the rest of the body. :)

   See a doctor!
