I suffer from kidney stones and have taken Vicodin and currently Norco for the pain. However, both drugs cause such severe upper GI pain that I am developing a fear of them. I have taken them with food, with milk, with yogurt, Pepto-Bizmo, and combinations of all of these trying to coat my stomach. Nothing helps. The pain starts just about 20 minutes after dosing and lasts for 3-4 hours. And now I am also developing a fear of the kidney stone pain and not having something to help. Any suggestions?
