Obesity is considered as the epidemic of the century. Central obesity is one of the metabolic syndrome's features. It has been proven that obesity can cause back pain and headaches; thus, there might be a link between chronic pain and the syndrome.

The objective of this study is to assess the prevalence of metabolic syndrome in patients suffering from chronic pain.

All patients will answer a questionnaire, their hip circumference will be measured, and their BMI will be calculated (weight/(height)2 ).

The patients' blood pressure will be measured. The patients will be asked to bring their blood tests (lipids and glucose).

Inclusion Criteria:

• Patients over 18 that suffer from chronic pain and are being treated at the pain medicine unit
