What Causes Palpitations And Pain In The Right Quadrant?

Hi I m a 35 yr old female, 5 7 and weigh 128. I have been a vegetarian my whole life, cholesterol 140, BP usually 110/70. I do have problems with heart palpitations, but my question is about right quadrant pain that I ve been having for about 3 yrs. It radiates to back, it s a gnawing, chronic pain. I feel nauseous, and just generally ill. I ve had barium swallow, endoscopy, hida scan, 2 ultrasounds- all normal. A few weeks ago my primary ordered a CT scan. He called and said my gallbladder is good, but my right kidney shows possible stone, so he referred me to the urologist, who said my right kidney looks swollen and possible stone in ureter. Sent me straight back over to hospital for a urn CT scan (lots of radiation), but he said he felt it was necessary. Nurse called me with results- right kidney is fine, cyst on left kidney, cyst on right ovary, what they thought was a stone is calcifications in ureter. Then she casually mentions there was some mild fatty deposits on liver. I freaked. She said oh everyone says that, but it s no big deal. Followed ip with primary, and I was grilling him about this fatty liver thing. He said, it s mild and wouldn t be the cause of my pain. So I m back at square one, only now I m freaked thinking I have a fat on my liver. First ultrasound I had done the tech said, beautiful liver ....second one I had done just a month before CT scan, and everything looked great. Are Ct scans better at detecting those types of things? Both scans were with and without contrast. I m a wine drinker, but just couple times a week, or sometimes it s twice a month. I do drink more than the moderate 2 glasses, but I don t know anyone who does that. Bilirubin- 0.4, ALT- 15, AST- 16 Blood work normal. Sorry so long, but how serious is mild fatty infiltration of the liver?? How long will it take to repair if I abstain from alcohol? And can the mild fatty liver cause this pain and sick feeling? I still have no answers, but I would like feedback on the liver results and if cysts on kidneys are normal. My doctor just prescribed Zoloft and sent me on my way.....which isn t helping anything,so frustrated.
