sure i have kidney stones, on average 6-10 a year, unfortunately i am treated at the VA which change their doctors ever 2 years, normally urologist, but recently kidney doctors, i question why they have me on two medicines which do about the same thing, oh the stones are calcium oxalate. omeprazole 2 x 20 mg a day for acid reflux . and Sodium Bicarbonate 650 mg x 2 a day for the kidney stones, i developed acid reflux after they treated me over the years. potassium Citrate always helped me in the past these new medicine have serious side effects, stomach cramps vomiting and diarrhea. any advice. going to a patient advocate this am to complain. oh and my favorite is they refuse to give pain meds and no muscle relaxers, since Oklahoma got nailed for abusing the drugs.
