The ED is never going to treat hypercalcemia or really any chronic problems. It isn't acutely life threatening unless very high so not on their radar.They aren't mini-PCPS.Unfortunately people have poor access and get stuck in the ED visit spin cycle with care never moving forward. I think you are on a goodish path now though.
Unfortunately, I had a pcp that seemed to believe that everything was either due to menstruation, things I was doing, or that it was due to my low mental health or that I was lying. But he was the only one my insurance would cover. As soon as I switched doctors I got referrals and scans and procedures but that only happened in November of last year.The Ed always said it wasnt that high and it wasnt something to worry about.
