I noticed the vitals thing too. Someone in excruciating pain would at least show something in her vitals. Maybe not. Mostly when I find someone crying I make sure to question the pain because that's not the typical adult reaction to severe pain. Guarding, rapid breathing, grunting...more typical in my book. Not that I'd discount it. My other concern with a young female who can't give me a solid medical history is if she's actually taking her birth control and if she could be pregnant (especially the way she keeps throwing out major medical conditions that aren't normal for someone that age). I've had young female pt's with ruptured ovarian cysts grit their teeth, insist on standing up to get on the gurney and refuse pain meds while someone with a twisted ankle will cry and whine until they get their 6mgs of MS which absolutely snows them before they will let me splint (granted it does make them a bit more manageable). It's always a hard call with when to use narcs. I can't tell you what I would have done with this pt without being there, but it could have gone either way. I'm still pretty new at this so my criteria seems to change on every call where pain management comes into play.
Oh, and welcome to the forums jomedic. I hear what your saying as I just stopped working in a "mother-may-I?" county and began working in one where we get to use our own training and judgment. To add to what you said, I've also never had a pt who after receiving pain management could no longer tell me where the pain was.
