An experienced nurse-practitioner and research consultant requests patients to fill out a standard questionnaire before and at 1 day, 1-11 weeks, and 3 and 12 months after the procedure. The patients will receive a folder including questionnaires for each of the first 11 weeks and will be contacted by telephone once every week and asked to fill out the questionnaires. The questionnaire consist of the VAS and NRS score and questions about use of pain medication. The VAS score is a 10 cm line pain score ranging from "no pain" to "worst pain ever", the NRS is a similar tool where patients are asked in 3 different ways to describe their pain between 0 and 10 where 10 is the worst pain ever. Other medical treatment is registered at 0, 3 and 12 months.
