I had the same type of pain which wasn't nice at all.
What healped me a lot was a ca. 50 ml 50:50 mixture of olive oil and lemon juice first thing the the morning.
Furthermore, I can recommend cat's claw tea. Buy the herb, soak ca. 20 grams in 500ml water overnight, boil it some minutes.
Within a few days my pain has disappeared. I presume you have sort of an inflammation in your gall bladder that will be relieved by cat's claw.
