A prospective study was conducted to assess the prevalence, severity and diagnostic utility of pain in patients with venous leg ulcers. A semi-structured questionnaire was completed by 140 consecutive patients in two specialist centres caring for patients with leg ulcers. A high proportion (64%) of the 94 patients with ulcers of purely venous aetiology reported severe pain; 50% of these patients were taking either mild analgesia or none at all. In 10 of 72 cases, leg elevation made the pain worse. Venous ulcers are painful. Pain in three distinct locations was reported by patients-within ulcers, around ulcers and elsewhere in the leg. The presence of severe pain does not necessarily indicate arterial disease or infection. Pain is, in general, inadequately controlled in these patients.
