Hi Yellow tail, Hyperalgesia is a a syndrome that can develop in some people, and is more often discovered in patients that have abused, missused, have unrealistic expectations of being pain free or are simply prone to this addictive type reaction/behavior.
The more you take the more you need is a simplistic idea subscribed to by addictionologist who only deal with people who have been hindered more than helped by these meds. If you spend enough time on the net you can find articles that support the most extreme views, Like beer is better for children than milk. We actually had local billboards sugesting that nonesense suported by PETA.
It by no means applies to everyone that takes opiates. Its more like some people can drink socially and never develop a problem where some people may start a lifetime of alcoholism with their first drink.
Their are other factors involved in hyperalgesia than simply taking opiates for a prolonged period of time. If it was an absolute cetainty that all doctors subsrcibed to, nobody should ever use opiates more than a couple days, or is it weeks... or months? Like any theory, not every doc believes in it and their is absolutely no proof that everyone will experience it.
I have no doubt some people experience it, but I also know that it doesn't occur in everyone just like some people are more prone to addiction than others.
When this theory is taken to it's extreme, all opiates should be reserved for hospice use and imediately post op. What is the right ammount of time these meds can be used after a failed 6 level fusion? 4 days, 2 weeks, 2 months? If it's that certain, you would be able to answer that question.
Since you cant, believing something you experienced will happen to everyone is an alarmist response that would cause more suffering than those that experience hyperalgesia. And yes I do believe that opiates are widely over prescribed, missused and abused. It comes down to whether these meds are causing the patient more harm than good. Sadly patients tend not to notice the harm untill they are in serrious trouble. Those that can go years without an increase and can now walk and return to work like myself, beg to differ with this extremist theory.
Good luck with your uniquely individual circumstance. Dave
