I have only been prescribed Fentanyl since 12/13/2010 and I still don't really know how to put them on right, although I have been reading and have a plan for improving the situation and I think my wife and I made great strides 3 days ago and hopefully today will add another 3 days in the plus column. My question is, has anyone had pain for a couple of days after taking the old patch off almost like the feeling of a bruise? I noticed today that some of my pain is related to just that. Any clues? Thanks, Michael
