I have Hemmorigic Polycystic Kidney Disease, very painful, 4 large cysts drained sine 2008. I m taking Kadian, Morphone based and it s not enough relief. Taking Tramacet for break through....I d like to try something else for pain but my DR is reserved on how strong she ll allow narcotics to be for treatment. What else can be good to use that is close to kadian and tramacet? Tramacet has acetaminaphin which i don t want to have in breakthrough meds. Thanks, Ann Elizabeth
