Anyone who needs oxycontin and vicodin for severe back pain or cancer pain can go to a pain management specialist and receive it around the clock. Look in your yellow pages.
With all due respect, that's 100% horse manure.
Yes, there are "pain management specialists" in the yellow pages. No, they do not just turn on unending spigots of painkillers even if you're in chronic pain.
They will prescribe painkillers on a short-term basis for temporary pain like post-surgical pain, but long-term pain issues they withdraw the painkiller prescriptions after a few months and the "management" part comes into play, which is little more than encouraging the patient to "suck it up, nothing we can do for you."
I've got years of personal experience with this, because for years my wife had atypical acute chronic migraines (which literally did not let up for *months* at a time). Despite being reduced to a bedridden invalid from the crushing pain, the "pain management" doctors just shrugged their shoulders, saying that continuous painkiller prescriptions were simply not an option (for *any* patient except those who are going to die soon anyway).
And through chronic illness support groups, we meet dozens of other people who had had the exact same experience with "pain management" specialists.
So don't try to tell us how "anyone" who needs pain medication can "recieve it around the clock". Not for more than a week or two, anyway. After that, you're on your own.
