Premenstrual syndrome, commonly known as PMS, afflicts as many as 55 million women, making them irritable, achy, depressed, and anxious. According to the American College of Obstetricians Gynecologists, at least 85 percent of women with regular menstrual cycles have at least one PMS symptom. Unfortunately, just because PMS is common doesn’t mean it is well understood, and that puts women with PMS at a disadvantage: they may not know what is bothering them or how to get help. They think they’re forced to live with their symptoms. What’s worse, women with PMS are too often ridiculed or dismissed, when all they really want is relief.
