Contracted and high ejection fraction for gallbladder? What the heck?

2 ultrasounds have showed no stones but a contracted gallbladder, even after proper fasting. I figured I was going to need it out. My HIDA scan showed an EF of 97%, and my CT scan doesn't show anything abnormal. My doctors now think its an ulcer but the medication they gave me doesn't really help either. I get very nauseous and am hungry a LOT but I'm only 100 lbs (5'3" height, 25 yr old female). Why would I have a contracted gallbladder but a high ejection fraction? This seems very contradictory. I am getting tested for H Pylori soon as well.

Also, for about 36 hours AFTER the HIDA scan, I kept getting this prickly, pinching like, intermittent electric shock type  pain throughout my abdomen, through my back, sides, under my ribs. What the heck?

Just so you know, it has been months since my gallbladder. After doing plenty of research and NOT doing an endoscopy, it is either a wheat intolerance or anxiety. I do have chronic anxiety. I have managed to get the pain and sickness under control, but it was definitely due to stress. I am not sure if I am intolerant to wheat, maybe slightly because I cannot eat pasta without some major gas, but I have been eating healthier, sleeping better, and I have only had one other gallbladder attack over the holidays. I've managed to keep my gallbladder (for now). I am much nicer to it and realize the importance that stress plays on one's health.
