“Dr Greenspan did trigeminal neuralgia ablations with minimal local numbing... turns out thats supposed to be done under General Anesthesia. My first injection was 4 days after I had a stroke & 3rd & 4th degree full thickness burns! I was hospitalized with a totally deformed head, burns & such excruciating pain I attempted suicide Then gas lit into believing this was helping because I got a 7-10 of 50% reduction in pain.... how did i fall for this conman”

“Struggling with major back pain in your 20s sucks, but after going to several doctors and having injections into my spine to no avail, Dr. Greenspan has been a total diamond in the rough. The trigger point injections he performs have quite literally given me my life back, and he is so attentive and listens to your feedback on where you think might be best to inject. Highly recommend.”

“I tore three tendons in my right shoulder rotator cuff. My arm was painful and basically useless and I was unable to sleep on it. The usual treatment is surgical repair, which would have a long and uncomfortable recovery. PT saw no improvement. Dr. Greenspan suggested as an alternative, to inject stem cells into the area around each torn tendon. After almost 8 months since the injections, I am able to do pushups, hang on a pull-up bar, reach over my head and even sleep on it. I am able to return to my joy in my wood shop.”

“I have seen doctors for years hoping for help with arthritis, trigger point pain in shoulder area , and neck and lumbar spine extending to thighs..Dr. Greenspan is the first doctor that has totally helped me! I am so happy. I have felt better with each steroid injection. I have complete trust in his care. The staff is just wonderful too. They are friendly, helpful and knowledgeable every time I visit. Its so nice to still have a doc that listens. Thanks to all!”
