Find an ENT doc that is also a sleep specialist. I had positional sleep apnea and serious complications with my sinuses. I finally agreed to have Functional Endoscopic Sinus Surgery to basically rebuild my sinuses. Google FESS to get the lowdown on the surgery. The surgery is a big step to take because the first two weeks after surgery is not fun. But, now I can breathe normally through my nostrils and my apnea is non existent. Totally worth it for me. Insurance covered it. Age and 5 years of football caused the sinus damage.
