I am a 29 year old female with a history of drinking on the weekends since about age 20. I am 5'00" and 135 pounds. I am having upper right quadrant pain frequently, particularly after drinking. My liver enzyme tests have all been normal, and all other bloodwork was normal. An ultrasound showed a clear/normal looking gallbladder, liver and pancreas. The only note was a kidney stone in my right kidney. About a week ago, my doctor prescribed me Omeprazole 20MG twice a day. I have some relief, but I still have the pain after I drink even one beer. What could be the problem?
