Hello, Over the years I have been taking many medications for my endometriosis that causes severe menstrual cramps for days. I was told that I need to have surgery but, that's just not an option now and, nothing else seems to be working. I was told that vicodin may help my cramps? Is that true? I also have arthritus in my knee's. Will vicodin help with that as well? Thanks for your help and any suggestions!
