No Junkiegirl, it's a real phenomena and I believe it's called "hyperalgesia". It's definitely real and I especially used to have it when I was on high doses of OxyContin many years ago. Along with what you described above, I think it also has to do with damage to one's, I don't know, pain receptors. It can surely be responsible for increased tolerances and the desire to take more meds when you feel bad. OxyContin is one drug that I believe where the best course of action is "the least effective dose possible". In other words, if you get 50% reduction in pain from your current dose, taking another pill a day, for instance, will not increase your reduction in pain but the percentage increase in your meds. It may only be a trickle better, and so on and so on. You may have to increase your current dose by 500% to even get to 75% reduction and at that point the adverse effects would obviously outweigh any gain in pain reduction. I hope that makes sense OP.
