I have no real advice, but I work in the health care field. Sadly, "frequent flyers" to the ER do get treated this way. Pain is not something we can prove, unfortunately.
One thing you can do is contact the Joint Commission and make a complaint. They investigate concerns reported by family and patients.
I hope that you can find some sort of advocate to help you out! In the meantime,
