It seems that I am getting some relief from Lidocaine 5% patch now. My question is just how long can I use them. I know they are 12 hours on/12 hours off, but can I wear them everyday forever? Oxycontin 10 mg. every 12 hours with Oxycodone 5 for break through every 4 hours. I requested an updated MRI and my pain management didn't think that was necessary as I am not a good candidate for further surgeries, had failed back surgery syndrome after my fusion in 2015.
