I found out I had gallstones after a 70 mile hot ride.
A few hours I was in A&E doubled over and vomiting as I was in the most ridiculous pain imaginable.
After an ultrasound the next day, they told me I had a infected gallbladder, five days in hospital getting the infection under control, then four weeks of an almost zero fat diet (chicken breast salad etc) I had it removed privately.
I then could not produce solid motions for three months so am now on prescription bile acid sequestrants for the last four years, apparently according to my consultant, I was one of the unlucky 5% who need the medication.
If you can go private, I was told it’s a better option as the surgeon will x-ray the bile duct as well to make sure there are no residual stones left in there, he said that on the NHS, they don’t do that, so you can be left with pain even after have the gall bladder removed.
Good luck!
