Is Endocet an ok pain reliever for the day after a kidney stone moved- my bladder just feels sore now - but my side pain has ceased. I had taken one naproxen last night which seemed to relax me and allow for sleep - obviously I drank tons of good health food cranberry juice and water all day yesterday, stayed quiet and now this morning I feel some slight irritation of the bladder - but Radically better than yesterday. Is it ok to take one tablet of Endocet today to keep things relaxed as long as I keep up the constant flow of fluids and a lite diet?
