During pregnancy, your breasts may be tender and even experience sharp, severe pain. It is one of the earliest signs of pregnancy, which usually starts between 4-6 weeks due to increased hormonal activity. Women often describe it as a more intense version of the premenstrual symptom. The discomfort may also spread to your nipples and areolas (the dark area around your nipples).
What is the reason of this?
Your breasts may soon be your baby's sole source of nourishment, so there is a lot of activity going on to prepare them for the role. The increase in estrogen and progesterone, along with higher overall blood flow to the area, causes you to feel more pain than usual. They also build up fat content that can make them grow to a cup or two size. You may experience some itching or see cracks from the growth.
Tips
Breast tenderness is most common at the beginning and end of your pregnancy, so you can be sure that you won't have to worry about this symptom for 9 months. It is a good idea to wear a comfortable bra for exercise and daily activities so as not to increase discomfort; Maternity stores often have a great selection of pregnancy sleep bras. You may want to practice the `look, don't touch` rule on your partner until the pain subsides. There are no medications designed to treat this symptom. Vitamin E has been theorized to provide some relief from breast tenderness, but as always, it's important to consult a healthcare professional before starting any new dietary supplement during pregnancy.
