PMS is a party and a half, isn't it ladies? We break out, have crazy mood swings, crave sweet and salty treats, become exhausted, get major menstrual cramps, have headaches and backaches, and one of my personal favorites — bloating. Some women experience sore breasts too, but why is that?
A week or so before your period arrives, your body begins producing oodles of estrogen and progesterone. Those hormones are what cause all these fun symptoms. During this time, your body retains water, which is what causes you to become bloated. Rings, shoes, or pants may feel tight because your body swells with this extra water, which also makes your breasts swell. All that fluid forces your breast tissue to expand, which stretches the nerves that cause that painful and achy feeling.
Soon after you get your period, the soreness should disappear. If the pain is really bad, you can take an OTC pain reliever such as ibuprofen. Wearing a more supportive bra, like a sports bra, will prevent your breasts from moving too much, which can also reduce tenderness. Cutting down on salty foods can offer relief since eating excessive amounts of salt will make you retain even more water.
