I feel for the OP and people in that situation. My 90 + yr. old FIL has chronic severe back pain and been through all sorts of back and other surgeries. About 3 or 4 years ago they forced him off of Morphine. I believe he was using it responsibly and it gave him some partial relief. Since then, he's been to every pain specialist in 30 miles including acupuncture, without any results. They now only allow him some Tylenol with codeine. I can think of no reason for his docs to do that. A friend's wife is in much the same situation with severe neck and back pain. I think she had once been on some sort of time release Morphine and was forced off.
Since most medical Doctors work for some sort of profit or non-profit corporation someone else is paying their malpractice premium. That may be part of the reason that opiate and opioid prescribing has been squashed. There have been countless prescribing abuses by medical practices, especially in the last 10 years. I recall one Urgent care center where everyone in the place was arrested but the receptionist. The whole fake heroin rehab clinic boom of a few years back was insane. Without going into all the financial gaming of parents that they did, several of them were cracked because the counselors were selling doses. So, the people who really need opiates get punished.
