You note a negative CT scan and negative hepatic panel and culture for H Pylori.
The next test I would consider would be an upper endoscopy. This would comprehensively evaluate the upper GI tract, looking for inflammation, an ulcer or any mass effect which may be causing your symptoms.
I would also consider an abdominal ultrasound to better evaluate the gallbladder and liver. Another test to evaluate the gallbladder function would be a HIDA scan with CCK stimulation - I would consider this test if there continues to be suspicion of gallbladder pathology with a normal ultrasound.
Other tests to consider would be evaluating the pancreatic enzymes and making sure chronic pancreatitis isn't the case (this disease, as well as peptic ulcers can cause pain radiating to the back).
In any case, the GI referral is the right next step. You may want to discuss these tests at your consultation.
Followup with your personal physician is essential.
