Yesterday I had severe pain in lower right abdomen and after the ultrasound they concluded there's a 4mm stone in right kidney (VUJ...I don't know what it means). So they gave a diuretic syrup (after breakfast, lunch and dinner - three times with water) and a capsule called urimax (before sleeping). They gave buscogast plus as pain killer. I had one tablet today morning at around 9-9:30. But it doesn't seem to work. It has reduced the pain a little but it is still paining. Which other pain killer can I take which wouldn't react with the medication I'm taking.
