What are some causes of dark urine and belly pain?

Biliary trouble: The first condition that comes to mind is blockage of the normal bile drainage into the intestines due to either gall stones stuck in the common duct or a pancreatic or papillary tumor causing billirrubin to rise in the blood and showing up in the urine. The presence of pain favors gall stones. Jaundice would be present.

So many : There are too many to go into. Dark urine could b from dehydration and and pain due to infection or inflammation can lead to dehydration. Other reason would b blockage or bile duct which leads to spilling of bile into urine making it dark. U need to b seen in person to figure out what's going on.

One has: To rule out problems with liver and gall bladder that could cause dark urine and abdominal pain, kidney problems as well as a rare condition called porphyria that can go with dark urine and also abdominal pain. I suggest go see a physician who should also examine you and run some tests. Good luck!
