What organ is inside the body on left hand side just near the top of the pelvis?
On the left: spleen, left kidney, descending colon, left ureter. On the right: liver, gallbladder, head of pancreas, duodenum, ascending colon, right kidney, right ureter In the middle: Stomach, tail of pancreas, transverse colon, major blood vessels (aorta, inferior vena cava) Throbbing sensation near top of pelvis on left: propbably nothing to worry about. Maybe muscular related to abdominal wall. Could be related to kidney stone as suggested by some people. Please see your doctor so that he/she can examine you and reassure you properly. Erm, Ken B, if you really are a doctor you should get back to med school and have a look at those anatomy textbooks again.
