Hi my name is Dayle, I have been on a Cpap for nearly 2 yrs now for Sleep Apnea. I have just had Sinus Surgery 3 weeks ago and I am really struggling with being able to tolerate the Cpap while healing form the surgery. I thought at first it was drying out my sinus which is not good for healing but I am now thinking my pressure may be too hard for me in this situation. My machine runs at 18. Has anyone had sinus surgery while using a Cpap?
