Sounds like it could be your gall bladder --

do you have your GB? Those symptoms sound like classic GB attack symptoms to me. I'd recommend an Ultrasound if you can get it -- you may have stones stuck in the bile duct. Your doctor can schedule one for you.

I had my GB removed in 2004 as mine was infected and in danger of rupturing. That was my fault moving all those stones around flushing and cleansing!!

Good luck!
