No, I haven't noticed either. I take ocycodone and have for years. I have tried Morphine and Oxycontin, Avinza and many many other long acting medications, but they all give me side effects and truly don't work as well as the oxycodone.
Recently I switched from Percocet to plain Oxycodone and have noticed that I need some ibuprofen sometimes in addition to the oxycodone, but other than that, no hyperalgesia.
Thank you for the post. Good one.
