Premenstrual Syndrome (PMS) is an important female problem that has been present since ancient times but we have not yet reached a conclusion about its definition, etiology, diagnosis and treatment. 

It is defined as physical and psychological distress and/or significant behavioural changes that impair the normal activities and social relations, which appear during the luteal phase of the menstrual cycle. Although it is believed that PMS is mainly of physiological origin, it may be related to biological, psychological and sociological reasons. 

Only tool that can be useful in diagnosis is the menstrual calendar. in addition to the family history, for at least 3 months the patient should be tracked and her data should be prospectively recorded. There are 3 important points to consider when diagnosing PMS: 
First, the symptoms should have a cyclic relation with the menstrual cycle; 
Second point is the repetitive feature of PMS,
Third is that the symptoms should be serious enough to affect daily life, activities and social relationships of the individual.
In this period, emotional swinging (such as laughing when crying), anxiety, tension, depressive mood, anger, irritability, decreased interest in daily activities, fatigue, difficulty in concentration, appetite change, tenderness and swelling in the breasts, headache, edema, joint or muscle pain, weight gain are most common symptoms.

Acupuncture treatment will be effective according to the main cause of these disorders. At the end of the 3rd month the symptoms will be reduced or disappeared.
