Been having pregnancy sytoms but iam not pregnant and one sytom is my breasts have been hurting and the left one hurts more why?
Other issues. Other issues can cause breast tenderness besides pregnancy such as taking more caffeine or taking hormones or eating more sweets or exercising with a poorly fitting bra. Decrease caffeine and see what happens. If the tenderness doesn't go away in several weeks or you feel a lump see a doctor.
