Pain innervation of the fundus (dermatome wise)

Cervix and upper vagina: S2 - S4
What does the pain in T12-S4 mean?
Pain in T12-S4
Uterus, rectum, cervix, vagina and bladder -> pain will be referred to the back, bottom, legs
- it will be a severe, difficult to localise pain
Is visceral pain easy to localise?
It is poorly localised - due to under-representation within the somatosensory cortex
What is a relation to visceral pain and autonomic NS sensations?
Nociceptors stretched -> possible autonomic NS sensations
*It may cause sweating and decreased BP
Visceral hypersensitivity
An injury to viscera -> viscera may respond by sensitisation of neurones -> neurotransmitter levels creating increased pain
