Brief Summary:
Nowadays, chronic pain mainly as a result of iatrogenic nerve damage is generally considered as the most frequent complication after inguinal hernia surgery. The primary objective of this randomised double-blind placebo-controlled trial is to investigate whether pregabalin reduces pain in patients with chronic pain of neuropathic origin after herniorraphy.
