Pain is a completely subjective experience. There is no test for it. Drug seekers can be very convincing in their drama. I’ve been taken many many times. I’d be happier if people could just go to the pharmacy and buy what they want, without an RX. If they want it that bad they will get it, one way or another.
By the way it’s not just dentists. My daughters neurologist has a sign in his office stating he will not prescribe narcotics for headaches. He specializes in migraine.
If your daughter is struggling with bad migraines, there is a med called Esgic which is very good at eliminating migraine pain. It's not very well known, so I thought I'd throw that out there if she's having bad migraines and striking out in terms of finding relief.
