I met with Dr. Tangco after a vertigo spell. I felt a terrible pain in my head and had to pull over from the freeway to endure a full vertigo attack within minutes. I couldn’t walk or see and an ambulance took me to the nearby hospital. Weeks later, I met with Dr. Tangco who gave me a series of tests that I flunked but decided to document in my file I may have been faking my results. She told me I must be dehydrated and gave me a water test to measure the liquids in my diet which included the broth in my soup. I left frustrated. I later met with Dr. Sergio Azzolino, Chiropractic Neurology Group in SF who is Board Certified in Pain Management in California. He gave me a series of tests for over an hour and again I flunked. His equipment and series of tests pinpointed the the damage was stemming from the back of the head and left side of left side of neck. I then remembered slipping on my driveway months prior. I was walking around with post concussion symptoms. The neck damage was from a previous ski accident and my nerves were not firing to my brain on that side of the head. Through therapy, home exercise and consistent adjustments I got my life back! My dizziness went away. Dr. Azzilino saved me. Dr. Tangco did nothing but make the rest of John Muir think I’m a fake and now question every time I see the general doctor. Thanks for nothing. A good doctor listens to the patients and actually tries to help.
