A group of symptoms that can happen with menstrual periods, most often between the release of an egg and a period.
The physical and emotional changes of premenstrual syndrome (PMS) vary from slight to intense. The symptoms tend to follow a monthly pattern. They most often go away within four days after the start of a period.
Symptoms include mood swings, tender breasts, food cravings, fatigue, irritability and depression. They also can include joint or muscle pain, headache, and belly bloating.
Lifestyle changes, prescription medicines and pain relievers available without a prescription may reduce symptoms.
