I have tried percocet, oxy, vicodin, Hydrocodone with tylenol, I currently wear a fentenyl patch 12 macrograms change every 3 days. All the pain meds I try work for a while 2-3 months then we are just swapping and going to one I haven't been on for a while. Any suggestions on a medication I can take that will last me longer than 5 hours and a couple of months?
