What the heck is wrong with me?

Hello...hard to reproduce your name, but glad you love him.

If you repost, might be a good idea to include your age. Different problems are more prevalent in different age groups.

The imaging of the thoracic contents by CT might not have been the best choice. CT is better for bony detail, while MRI is better for soft tissue problems and illumination. The tests you have had so far are good, though, for a start.

The location you are describing sounds like the appendix to me most likely. If you push in gently and suddenly release, does it hurt worse? If so, that's called 'rebound tenderness' and is a classic sign of appendix problems. If it's not that, then you might need a lower GI study.

Sometimes, although your don't have a gallbladder, a residual stone can stay in the ducts leading away from the gallbladder. But it wuld be picket up by the CT scan. It can't be anything too dangerous, since nothing picked it up and you don't feel too bad.

Is it constant? Does it come and go? Stabbing, burning, throbbing, aching? Is it localized or does it move around or radiate? My medical degree is only from Yahoo! Answers, so what did my colleagues who read the scan and your labs say?
