IIeana, I want to inform you and Dr. Farshchian what happened after my last stem cell treatment. When I got home and finished the last of the stem cell drops in my left ear my hearing aids failed and had to return to the audiologist. He initially snickered when I told him I had stem cells injected at the base of my ear for radiation treatment I just finished. After he did hearing tests, the first in four years, he apologized and told me my left ear improved by 13db and the right by 10db. I didn't believe when doctor Farschian told me not to be surprised if I didn't need hearing aids in that ear, but apparently he had a reason to make that statment. Thanks again for everything Bob.
