Dr. Paul Toffel, board certified ENT, sub-specialty in EBV. Glendale, CA. 818-790-3172 I came to him for sinus headaches. He later questioned me on my complaints of fatigue, and mental fog. He told me he suspected I had EBV/Fm. This was news to me, but it made sense. I had mono in college 20 years ago and have never been healthy since. He did extensive blood tests. The levels of various titers were proof I had EBV. He gives me 2 mg. shots every 3 weeks of GAMMASTAN immune-globulin. It is like getting a healthy person's immune system put in you. It's safe and carefully screened and FDA approved. Can't stress it enough how much this helped me. God Bless You Dr. Toffel!
