At first I thought this spine doctor/pain management doctor was having a bad or long day on my first visit. He was very cold, arrogant and disinterested. I have a very sore, bad , aching back from injuries caused by a fall. Of course he says my back is "unremarkable" and I don't need surgery which I never purported I did. He has awful bedside manner and generally a bitter disposition overall.
The second time I came in it was supposed to be a follow up, but I wanted to let him know my lumbar part of my back was really really hurting. So he examined it quickly and actually wrote and order for an MRI. That's the best thing that came out of this appointment. Once again, he was condescending, arrogant, rude and overall unpleasant.
I highly suggest not going to see this particular doctor if you have back issues. There are plenty of doctors here.
After my two experiences, I finally did a search...hah! Very low ratings and a few stories mimic mine.
