Dr. Kerkowitz did spinal surgery on my back, over 2 years ago. He did what they call a cage, to support my discs and decompressed 2 nerves, I did good for the 2 weeks past my surgery, followed all the drs. orders, then BAM all the pain came back. I went back to Dr Herkowitz he took an xray said nothing was wrong, its fixed, he was bullying & rude, I left in tears. I have a knot in the cage, no one can get to, I have sciatica down both sides. This has been going on for 2 years, I have been in pain! But ya I am fixed, so he says!
