Hi bob.......just read it.
2 things spring immediately to mind.
1) Diverticular disease (acute diverticulitis)
2) Leaking abdominal aneurysm ( as a 200-1 outsider.
he will need scans and an endoscopy, but would be interested to hearthe outcome.
1) Possible, but would diverticulitis cause pain in the groin and/or cause pain on palpation in so many areas?
2) Bi-lat BP fine, no melena, no pulsatile mass? Triple A was one of my instincts as well
Any idea if renal impairments would cause any sort of fecal upset?
