"Premenstrual syndrome is the name for a set of physical and emotional symptoms that severely affect women in the days leading up to their menstrual period. While many women may experience some discomfort and irritability during this time, some deal with debilitating physical and emotional distress that prevents them from living their lives
Premenstrual syndrome, or PMS, is usually diagnosed when symptoms have been present for at least the last three menstrual periods. These symptoms will usually begin within one week prior to starting your period and end within approximately four days after menstruation begins.

Skin problems/acne flare-ups
Swelling in the feet and hands
Changes in appetite
Weight gain and/or bloating
Outbursts of anger
Overall emotional instability and/or severe mood swings"
