For some, the physical pain and emotional stress are severe enough to affect their daily lives. Regardless of symptom severity, the signs and symptoms generally disappear within four days of the start of the menstrual period for most women.
But a small number of women with premenstrual syndrome have disabling symptoms every month. This form of PMS is called premenstrual dysphoric disorder (PMDD).
PMDD signs and symptoms include depression, mood swings, anger, anxiety, feeling overwhelmed, difficulty concentrating, irritability and tension.
