question: hi I suffer with chronic back pain after a serious car accident, I have been prescribed kapake 30 / 500 mgs by my doctor 1-2 tabs x 4 times daily as required. They made me sleepy / drowsy, but a good pain reliever. We then tried Tramadol 50 mg, same dosage, I found these more effective than kapake for pain relief however when I take them I have urinary retension, even when I take small doses. I would like to know if there is an alternative drug that would give me the same relief as tramadol (not codeine) without the urinary retension issues.
