Something on my right side, near the bottom of my ribcage, hurts a bit after i drink. liver function tests show no problems. what might be going on?

Some other: possibilities include gallbladder disease, gastrointestinal ulcers ,and gastritis. I see your doctor again and tell him it is worse when you drink, possibly after eating fatty foods as well? If so, that might point to the gallbladder. An ultrasound might be the next step. Also, it may be a good idea to look inside the stomach with a camera. You might need a GI referral. Best of luck!
