Hi, I know it's been a while, but I'm still around, just been trying to do some research.
Problem is, I've only found rumors and hints. I have heard that there is a study that shows opioid use actually causes more pain. The study is supposed to claim that the way opioids interact with the brain's chemistry only reduces the pain for very short intervals and then tricks the brain into feeling even more pain than is actually there.
It also seems to show that the safer forms of pain relief, Tylenol, aspirin, etc. are actually more effective than previously thought. Of course, ice, elevation and rest, with even more emphasis on elevation than anyone seems to like, are critical to recovery. I use a foam wedge pillow and have even been known to sleep with it. It really helps with the swelling and has helped me with my left leg get at least 4 weeks ahead of where I had been with my recovery with my right leg.
I follow the belief that this my leg, my recovery and my pain, so no one else has a better idea of how to go about this recovery.
