Visceral pain

Visceral pain originates from internal organs such as the intestines, bladder, or uterus.

It is typically diffuse, poorly localized and often accompanied by referred pain to other body regions. Patients often describe it as cramping, pressure-like or deep aching.

Because visceral pain is mediated by complex neural and autonomic pathways, it is difficult to diagnose and treat. It plays a central role in disorders such as irritable bowel syndrome, endometriosis and interstitial cystitis. Visceral pain highlights the overlap between peripheral and central mechanisms of pain, as well as the influence of autonomic imbalance.
