Brief Summary:
This trial will test the effectiveness of amitriptyline in relieving chronic pain of adults that have had an amputation

Condition or disease Intervention/treatment Phase
Amputation, Traumatic Pain Postoperative Pain Drug: Amitriptyline Phase 4

Detailed Description:
This double-masked placebo controlled trial will randomize patients (n=125) who are 6 months or more after amputation and have a 3 or more month history of pain to a daily dose of amitriptyline or a placebo for 6 weeks.
