Comments: I have no words to express my gratitude to Dr. Mauricio Herrera. After two years of constant pain and two unnecessary lumbar spine surgeries - since that wasn't the source of my pain - I finally found his clinic. From the very first appointment, Dr. Herrera correctly identified the true origin of my pain, something no other doctor had been able to do, and he understood why no medication was helping. In less than a week, my surgery was scheduled, thanks also to the tremendous support and dedication of his assistant and team, who did everything possible to expedite the process and alleviate my pain as quickly as possible. From the day of the surgery, my life changed completely. I stopped feeling bitter and frustrated; at 47, I felt like I was 90, and today I have regained my joy and quality of life. Thank you, Doctor, for giving me back the joyful person I once was. I will be eternally grateful.
