There are so many questions I have about your case. When was your procedure? What is your status now? Does anyone know what happened?
I know a lot of happy Dr. Filler patients and a few who are not so happy. That is true for all the doctors I know. It doesn't surprise me to discover some lawsuits... do thousands of procedures and you are likely to have disasters (both with and without mistakes on the doctor's part.)
One of my favorite quotes from a surgeon's conference was....
"If you give enough haircuts, someone will die in your chair"
I'm so sorry that you've been through such a horrible ordeal. Spine is such a poorly understood field of medicine and unfortunately, such stories are not as rare as they should be. I hope you have found some relief.
Welcome to the forum. All the best,
Mark
