 At baseline, patients will be asked to fill validated quality of life questionnaires EQ-5D, AVVQ and CIVIQ and will have their clinical scores assessed using a validated scoring system CEAP and VCSS. On discharge after their varicose vein intervention, they will then be provided with a diary to record their post-procedural pain every day for 10 days using a validated visual analogue scale VAS as well as to record when they return to their normal activities and are back to work. They will also be asked to attend a follow-up in 2 weeks and at 6 months.
