Pain on the ride side

"Right side abdominal pain is commonly caused by conditions such as appendicitis, gallstones, kidney stones, constipation, ectopic pregnancy, ovarian cyst troubles, endometriosis, Crohn's disease, ulcerative colitis, trapped wind, kidney infection, pulled muscles, hepatitis, and a number of other rarer diseases." hi monarch, not sure if these conditions are possible with you or apply but a start.  I bet its gas

As a test, Monarch, if you will buy some high quality apple juice and drink quite a bit of it for a couple of days, you might find out if gallstones are the problem. The apple juice would soften the stones, giving you temporary relief from a stone stuck in the duct. Do, please, get high quality apple juice,...not the highly sweetened 'apple juice' from concentrate. That stuff gives me a headache and makes me 'sick as a dog'. Locally, I get Martinelli's unfiltered apple juice, R.W. Knudsen, or one of the Whole Foods gallons. I prefer unfiltered with No sugar added. ...or eat apples.

Mikeq, CT scans won't always show gallstones, even when you do have them. Gallstones don't have to be rock-hard and calcified in order to cause trouble. The 'stones' can be lumps of cholesterol (not calcified stones), yet block (or slow) the flow of bile. Please Google 'radiolucent gallstones missed'.

"Cholesterol stones (80% of all GB stones in the UK) are large, often solitary and radiolucent."

The solution, in my opinion, is to do a "liver flush". Please Google "liver flush" (and I'm not talking about the colorful little expensive bottles of drops and boxes that come up at the top of the Google search). A real liver flush takes at least a day and a half of your life ---but so much better than going to the hospital to have a gallbladder removal.

You've done something important. Gallstone pain can be incapacitating. I suggest you look up "liver flush". Done properly, this expells debris from the gallbladder and liver, leaving you with nice clean ducts.
"Fruits in general have malic acid, but it's especially abundant in apples. Ninety-four to 98 percent of apple's total acid comes from malic acid, according to Bartek.ca. Watermelon is another great source of malic acid, with 85 to 95 percent of the total acid content. Apricots, bananas, blackberries, cherries, grapes, kiwi, lychees, mango, nectarines, oranges, peaches, pears and strawberries are other fine choices."

"What Everybody Ought To Know (But Doesn’t) About Heartburn & GERD

In this first article I will present evidence demonstrating that, contrary to popular belief, heartburn and GERD are caused by too little (not too much) stomach acid. "
