Brief Summary:

This study will be looking at the effect of compression therapy in patients having endovenous treatment for varicose veins using foam sclerotherapy. Patients will be randomised to either the compression group (group A) or the no compression group (group B).

The pain scores, compliance, quality of life scores, occlusion rate at 6 months as well as the cost effectiveness of each intervention will be assessed.
