The short explanation
Breast tenderness and bloating in the week or two before a period are common physical symptoms of premenstrual syndrome. They are linked to normal hormone changes in the second half of the cycle, which can make breast tissue swell and the body hold on to a little fluid. They usually settle once the period starts, just as you describe. Things that help many women include a well-fitting supportive bra, regular physical activity, reducing salty and processed foods before periods, staying well hydrated and cutting down on caffeine. If symptoms are troublesome despite this, a clinician may suggest treatment options.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Keeping a short diary for two or three cycles shows whether the symptoms clearly follow your cycle, which helps a doctor decide what might help.
- Breast pain that does not follow the cycle, is in one specific spot, or comes with a lump, skin changes or nipple discharge should be checked separately.
- Hormonal contraception can make breast tenderness better for some women and worse for others.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your symptoms are only PMS. A doctor can examine you if the breast pain is one-sided, constant or comes with a lump.
