Investigation of neuropathic pain in treated leprosy patients in Ethiopia: a cross-sectional study.

Pain can be a significant problem for treated leprosy patients. It can be nociceptive due to tissue inflammation occurring during episodes of immune mediated reactions, or neuropathic due to leprosy affecting the somatosensory system. There are sparse epidemiological data on the prevalence and impact of neuropathic pain in treated leprosy patients.
