He diagnosed me with being hooked on IV fluids and drug seeking. I was vomiting and I didn't know why. He made it hard to get a 2nd opinion. I finally recently found out that I have Hyperparathyroidism. Since I had it for so long, I might have damage to my kidneys and my bones. This doctor is the worst doctor I've ever seen.
