Bounce-back pain (I think they've called it here) is common when withdrawing from opiate
pain-killers. It can be more severe that the original pain for
which the medications were used. This could also be your problem. Are you working with a medical practitioner on your tapering, or doing it alone? I, personally, have been going it alone, and today I feel like my back is breaking, and that's not what I took Tramadol from in the first place...I took it for pain in my knees.
