Premenstual syndrome is a collection of physical and psychological symptoms most women will experience in the few days leading up to their period.
However, the severity and duration of the symptoms can vary dramatically and can have a huge impact on quality of life and negatively affect work/education, relationships and activities of daily life.
In women with more severe symptoms, it is vital to get the correct diagnosis taking account of timing, severity and nature of the symptoms to provide an individualised treatment plan.
