Premenstrual Syndrome. A combination of distressing physical, psychologic, or behavioral changes that occur during the luteal phase of the menstrual cycle. Symptoms of PMS are diverse (such as pain, water-retention, anxiety, cravings, and depression) and they diminish markedly 2 or 3 days after the initiation of menses.
For the purposes of clarity we will use the lower case pms for pre-menstrual syndrome and the upper case PMS for post menstrual syndrome. The definition of Post Menstrual Syndrome is the presence of one or more hormone induced irregularities in the two weeks after a woman finishes her period. This is often call Post Menstrual Dysphoric Disorder.
