somatic
What is the type of innervation of the visceral peritoneum?
- autonomic sympathetic
- parasympathetic
How does pain caused by inflammation tend to present?
- constant pain ‘aching’
- made worse by movement
- persists until inflammation subsides
How does pain caused by obstruction of a muscular tube tend to present?
- colicky pain ‘griping’
- severity fluctuates
- movement to try and get comfortable
How does pain caused by prolonged obstruction of a hollow viscus (causing distension) tend to present?
- constant stretching pain
- different from the ache of inflammation and not colicky, sign of future ischaemia.
What type of pain would ureter problems present with?
colicky pain
What type of pain would liver problems present with?
constant pain
What type of pain would biliary colic present with?
colicky
What type of pain would spleen problems present with?
constant
abscess or rupture
What type of pain would kidney problems present with?
constant
abscess, pylonephritis
What type of pain would bowel obstruction present with?
colicky
Why is biliary colic not actually colic?
intensity and minor fluctuate rather than actual fluctuations
When does colicky pain become constant?
ischaemia
Where does biliary colic pain tend to radiate?
through to the back, on the right
Where does epigastric pain tend to radiate?
straight through the back (retroperitoneal structures)
In what disease does sitting up and leaning forward relieve the pain?
pancreatitis
Where does left hypochondriac pain (tail of pancreas) tend to radiate?
through to the back, on the left
Where does right lumbar (kidney) pain tend to radiate?
in the loin and radiates to the groin (from the kidney, through the ureter towards the bladder)
Where does umbilical pain tend to radiate?
doesn’t normally radiate (due to being mostly visceral innervation)

in the loin and radiates to the groin (from the kidney, through the ureter towards the bladder)
What condition can present with ureteric colic (only on the left)?
abdominal aortic aneurysm
Where does lower abdominal pain tend to radiate?
- rarely radiates
- pain from deep in the pelvis structures refers to lower back/perineum
Generally, where does colicky abdominal pain radiate to?
the centre of the abdomen due to visceral sensation
Generally, where does pain from parietal inflammation radiate to?
doesn’t tend to radiate, only felt over the inflamed area
What does radiating pain indicate?
other structures are becoming involved
What may happen with small bowel pain?
- no radiation, but pain may move
- as somatic and visceral nerves become irritated
How does pain from appendicitis tend to preset?
- initially central
- shifts to the right iliac region
