Nasal and ear issues

Hi! Have cpap but its causing ear problems, had severe sinus infection, then ear probs, its awful????

What specific symptoms are you having?
What machine are you using?
What pressures are you using?
Are you using a humidifier and if so at what setting?
Using a heated hose?...if so at what setting?

Impossible to offer any constructive ideas without having more information from you

First thought about the sinus infection though...possibly related to humidity..either not enough or too much because either will give someone symptoms of a sinus infection (nasal congestion, drainage, pressure, etc)...unless of course you are having yellow/green/brown drainage and that's a real infection and unrelated to cpap usage.

Just cut and paste these in for starters.
