Hi, Welcome to Health care magic forum. Oxylite pro has nothing to do with the kidney stones. it has many side effects, but not the kidney stones. The pain could be due to the arthritis of the hip joint, or may be the kidney stones in the ureter. I advise you to consult an orthopedic surgeon for diagnosis and treatment . You may need to have an M.R.I and other tests for diagnosis. I usually prescribe to my patient with such symptoms injections of vitamin B1,6,and 12 for10 consecutive days, and then periodically. protein supplements, calcium, multivitamins, diclofenac, and paracetamol. Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods. Wishing for a quick and complete recovery. Thank you.
