My right side hurts just below my rib after drinking alcohol. Not bad, just like a sour stomach only on the wrong side. My liver numbers are good.?

Get checked out. Pain is the way your body lets you know there is a problem. The relationship to your drinking is no accident. This could be anything from an ulcer, to a problem with your gall bladder or pancreas. You need a physical exam from your primary care physician as soon as possible.
Look elsewhere. Check for other reasons. See your md re: ultrasound of gallbladder and liver. Check for medicines for refluf. Give the alcohol a rest!
