Most women have chest pain and this is the fact already. One of the reasons we all know is that it is related to periods that cause swelling and pain due to the level of hormones in the body. It can also affect the trainer, which is happily a temporary pain. But one of the reasons that causes chest pain is the use of coffee.
Experts say the breasts are sensitive to coffee due to "small canals" in the chest area, which in some cases can be boosted by stimulants such as caffeine or chocolate. This swelling causes pain. So if you feel that your chest hurts you after you have consumed coffee, make a visit to your doctor if you have to exclude coffee from your day.
