After months of misdiagnosed chronic back pain, I was referred to Dr. Hung at HSS by John Englehart. Dr. Hung reviewed my MRI and CT scan and after a physical examination, I was diagnosed with inflammation in the SI joint which he believed was causing referred back pain and sciatica. After two injections and a program of Physical Therapy, I am pain free. Dr Hung is smart, kind, and compassionate. Every day that I wake up without pain I lift up a silent thank you to Dr. Hung.
