Hi!
If you have had unprotected sex and have missed your periods, you could be pregnant. Hence check for pregnancy. Generally breast pain that comes and goes and disappears in between is due to fibroadenosis. This is a benign condition and often there is no lump associated with it. It generally responds to drugs like Danazol. It is often a symptom of pre menstrual syndrome. Pain felt primarily under left breast is often due to acidity and gastric reflux. It can also be due to costochondritis since you have a past history of injury. Wear good support bras. Please consult your gynecologist. Take care!
