I've had very severe stomach pain and vomiting for months now. had colonoscospy and endoscopy scheduled but had insurance problems. what could it be??

Ulcer?: The symptoms you report sound like those of someone with a stomach ulcer. While waiting to get your endoscopy done, your doctor might consider ordering a stool test to look for the H pylori bacteria that causes stomach ulcers.

Need testing: Hard to say what's going on. continue testing. Figure out your insurance situation a sap. Best way to go to re. Most of the er have social worker who can help u figure out payment situation.
