Experiencing back pain 3+ weeks. Went to ER. They found kidney stones in ct scan. I treated it myself with lemon juice Apple vinegar heating pad. They started to drop to buttock and then disappear. One is still in buttock. Won't move. What to do?

See your doctor. who may refer you to a urologist for further management, you don't want to self treat a kidney / ureter stone without medical supervision, if it is an insurance problem, go back to ER or seek help in free clinics / University/, teaching hospital, wish you wellness.
