Pain associated with venous ulcers in injecting drug users.

Pain is a concern among people with venous ulcers. Although the prevalence is unknown, venous ulcers occur in those who have a history of illicit injecting drug use. The purpose of this study was to (a) examine the relationship between venous ulcer characteristics and pain severity, (b) ascertain factors that cause pain, (c) determine methods to alleviate pain, and (d) explore beliefs about pain medications among people with a history of injection drug use. Thirty-two patients answered pain and demographic questionnaires and had their venous ulcers traced onto plastic to identify wound area. Greater current pain, worse pain in 24 hours, and higher levels of pain relief from medications were significantly related to larger wound areas. Ibuprofen, compression dressing Unna's boot, and heroin ranked highest in decreasing pain. The most painful activities were working, walking outside, standing, and stair climbing. Many patients (41%) did not like to bother others with their complaints of pain. Participants were generally satisfied with pain treatments and the response of care providers to their pain. People who have used injected drugs and have venous ulcers do have pain. Therefore, research must continue to evaluate this pain as well as the best ways to treat it.
