OUCH Sorry to hear about all that pain. I'm NOT a doctor but with all that Tylenol in your Percocet & the Vicodin, you could ask for oxycodone straight without any more Tylenol and add that to the mix. I found the 20mg sustained release ones balanced out the other pain pills well.
I assume you are on PEG?
