I have recently started seein a paib management doctor for disc bulging and arthritis in my back. We started in July with Norco and I have been experiencing break thru pain and they have started having me add MS Contin XR. I thought that we are not supposed to have extensed release medications. I don't feel that it helps much. I had RNY gastric bypass in 2009. Any helpful suggestions I could mention to my doctor. He is aware I had this procedure so I'm not sure extended release os the best option.
