Patient
CPAP can give you sinus infection. New equipment 3 times, sinus infection 3 times. By the 3rd night, each time I was sick. I had to take more antibiotics (not prescribed by Dr. Garfield) in 9 months than in my entire life, which, through blood tests, damaged my liver. Each time I told Dr. Garfield, about the problem, he continued to tell me I was wrong. Now my liver is, hopefully, in recovery mode. Sinus issues don't happen to everyone, especially within 3 days of new equipment. If it does happen to you, find a doctor who will listen, a Doctor who will find out why, and a Doctor who will seek alternatives.
