While I was under Dr. Greenberg’s care, getting PRP injections, I noticed that I started having more serious allergic-like reactions and nausea as time went on. I eventually saw a specialist that diagnosed me with MCAS. The specialist told me that surgery and stress events often raise the baseline level of MCAS, and while the baseline level might lower after the event has passed, it typically won’t recede all the way down to the original baseline level. I’m very suspicious that my PRP treatments raised my baseline level of MCAS. Furthermore, since you need mast cells to heal tissue injuries, having a higher baseline level of MCAS typically means that your tissues and wounds will heal slower. It’s my theory that the PRP treatments were initially healing my tissues, but making me a poor tissue healer in the long run. Unfortunately, MCAS is a fairly newly recognized syndrome, and we don’t know a lot about it. Some people theorize that perhaps if you take medicine to stabilize your mast cells while doing PRP treatments that you’re less likely to raise your baseline level. I don’t know if that’s true or not, but if I was ever to do PRP again, I’d go to a different doctor (one that uses ultrasound), and I’d be on medicine for MCAS before getting those injections done.

After a 2 year struggle with disabling low back pain caused by SI joint dysfunction I have finally found relief! I ran the gauntlet of all the conventional medical tests therapies and injections to treat chronic low back pain which ultimately ended in a bilateral SI joint fusion. Still I was dealing with disabling pain, so I continued to search for relief and finally found Dr Greenburg and his regenerative medicine practice. Over the last few months of working with doctor Greenberg I have regained my physical life and am no longer a slave to pain! My quality of life has greatly improved and things that I thought I would never do again such as hiking, cycling, swimming, yoga and surfing, are now a regular part of my life again.
If you're living in chronic pain do yourself a favor and don't waste time with all the conventional therapies, that only treat the symptom rather than resolve the structural issues. Doctor Greenberg's regenerative injections have been miraculous for me and I wish I hadn't wasted so much time and money pursuing deadend solutions. Thank you Dr Greenburg for keeping my hope alive and helping resume a joyful life!

Dr. Greenberg is way better than the majority of doctors I’ve gone to for my problems, but I’m still not satisfied with the treatment I’ve received from him. He truly has a gift in his ability to examine a body and know where a patient is feeling pain. However, knowing where someone is feeling pain isn’t the same as knowing where something is damaged. After getting multiple PRP treatments by him and having success at the beginning but eventually plateauing, I asked Dr. Greenberg multiple times if ultrasound would show my ligament damage. He told me that it would not show my damage. Eventually, I got tipped off by one of his ex-patients that told me that Dr. Greenberg had hit one of his nerves (I’ve been told by other prolotherapists that it’s easier to not hit nerves if you use guided ultrasound while doing injections), and that he’d started going to someone else and found out that Dr. Greenberg hadn’t injected the right place because of where fluid showed on the imaging. That made me decide to get my problems checked with ultrasound. At that appointment, I found out that my obliquus capitis inferior muscle was torn and that Dr. Greenberg hadn’t injected it at all. There was also damage in my upper back that showed on ultrasound. I talked it over with Dr. Greenberg, and he told me that just because there was damage there didn’t mean it was the major source of my problems. However, I don’t know if I agree with that because the other prolotherapist I saw said that because Novocain injected into my OCI lowered my pain and because muscle relaxers helped me reduce my pain, there was a good chance that it was a significant contributor to my pain. I haven’t had enough injections into my OCI to know who is right (I’ve only had one round of injections), but I’m very disappointed in the way Dr. Greenberg initially answered my questions about ultrasound. I understand that I did ask about ligament damage, and the way he answered could have been interpreted that he was telling me that my ligament damage wouldn’t show (and it didn’t), but he made it out like it was so useless that I was under the impression that nothing would show. Plus, he was completely unaware that my OCI was torn. That’s the major reason I have an issue with his practice but there also have been a few other red flags. He prescribed me a supplement I shouldn’t have been taking because of my food allergies. He also told me that even if my testosterone was at absolute zero, he wouldn’t give me testosterone because I’m female. All that being said, my pain levels are lower than when I started with him, and I don’t have any lasting physical damage from his treatments.
