	abstract = {BACKGROUND: Nerve injury is a main cause of long-term morbidity following blood donation, but little is known about symptoms, impact, prognosis and underlying cause., MATERIALS AND METHODS: A questionnaire, designed to characterize pain and estimate the prevalence of neuropathic pain, was sent to all blood donors registered with a complication related to 3 297 674 blood donations in Denmark from 2000-2009, with a local complication mainly characterized by pain, with severity grade {\textquoteright}long-term morbidity{\textquoteright} and imputability grade {\textquoteright}definite{\textquoteright} or {\textquoteright}probably{\textquoteright}., RESULTS: The questionnaire was sent to 152 donors (46 per 100 000 donations). Response rate was 88/152 (579\%). At the time of the questionnaire, which was between 12 months and 10 years after the blood donation, 69/88, who responded (784\%) still experienced symptoms. Of the 69 donors with persistent symptom, pain occurred in 51 donors (74\%) was moderate to severe in 24/69 donors (35\%) and had an impact on daily activity in 17/69 (25\%). Neuropathic pain was estimated to be the underlying cause of symptom in 30-52\% of the 69 donors with persistent symptoms, using three different systems for estimation, corresponding to 06-11/100 000 donations., DISCUSSION: Although a rare complication, nerve injury after blood donation may lead to long-term morbidity and may become chronic in a small proportion of donors. The most common symptoms are pain, and we estimate that neuropathic pain can be the underlying cause.Copyright {\textcopyright} 2015 International Society of Blood Transfusion.},
