<human>: Can you provide a brief rundown of the text in within 3 sentences?

My partner is a caucasian male, 34, 6'2", 200 lbs.

In March 2015, had gallbladder removed after a few months of vague pain, and 2 days of very concentrated RUQ abdominal pain. 

Laparoscopic surgery, area was more inflamed than the surgeon expected. Stayed an additional night with a drain. 

Was out of work for 3 months due to residual pain in the same area as the GB pain, and nausea. Pain will persist for days at a time, nausea for up to 24 hours. Sometimes following eating, sometimes not. At times it's worse now than before gallbladder removal.

We have since been to 2 hospital systems (ER twice after initial entry) and numerous doctors, including GPs, general surgeons (specializing in liver/GB area), and gastroenterologists. The pain clinic said they couldn't help him. Have had the following tests, all of which were normal except where indicated: 

* Endoscopy (found gastritis and ulcers, prescribed pantaprazole, which has helped with chronic heartburn)
* Endoscopic ultrasound
* MRI
* X-rays
* CT scan
* MRCP
* Gastric emptying test
* Blood/urinalysis

Every new doctor we go to says "it's part of the healing process," "everybody heals differently," "drink more fluids," "take more anti-depressants," and, most infuriatingly, "you shouldn't be feeling like this."

SO what do we do now?? I don't even know what kind of doctor to go to next. Nobody believes him, sends him for a test believing that it'll come back negative, and then washes their hands of us.
<bot>: Doctors don't believe residual post-cholecystectomy pain and nausea is serious, can't find anything wrong with him. What do we do now?
