You don't have to suffer the swelling every month. In fact, there are a number of ways to treat it. Premenstrual syndrome occurs during the last two weeks of the menstrual cycle, right before the period begins. During this time, a woman's levels of the hormones estrogen and progesterone rise. Luckily, there are many ways to deal with the problem, depending on how severe your symptoms are.
Caffeine tends to increase both swelling of the breasts and water retention.
Consider taking a multivitamin and calcium daily. But some intriguing research suggests that these nutrients may help remove water from the body and alleviate swelling in the breasts. Consider evening primrose oil supplements. These medicines contain pain relievers and natural diuretics, which can alleviate discomfort. If nighttime is especially uncomfortable, try sleeping on your back to protect your breasts from the painful compression you might feel when sleeping on your side or front.
