There is a thread I started on p. 2. I believe it's called "My Opiods Aren't
Working" On that thread you will find something that Hello~Kitty posted
to explain the problem. It's called Opiod-Induced Hyperalgia. You can
also find it on Wikipedia. (Sorry, I couldn't move it over for convenience)
It's difficult to understand but worth reading over if you're still in pain after
taking your opiods. Thank you Hello~Kitty.
