– The Use of Antidepressants in the Treatment of Irritable Bowel Syndrome and Other Functional GI Disorders https://www.med.unc.edu/ibs/files/2017/10/IBS-and-Antidepressants.pdf

First, you should not develop chronic pain after surgery. If pain persists after six weeks, check with your doctor concerning causation of pain. Antidepressants do not treat pain (at best, they make you a bit numb and distance you emotionally from psychic pain), and it becomes very hard to withdraw from the SSRIs and SNRIs, so better never to start them. The older tricyclic antidepressants in very low doses cause you to be sleepy and thus help with sleep. (Other sleep meds are often addictive, so this is a good choice if pain is making it hard to sleep.) Of course, all medications should be discussed with your doctors. Remember that they are often quick to prescribe and slow to deprescribe.
