What to do if my nose becomes sore from using a nasal pillows system?

It is important that you are using the correct size of pillow and humidification. Nasal pillows should have a secure fit. If you are using nasal pillows that are too large, the pressure and flaring of the nostrils will cause irritation. Using nasal pillows that are too small allow for excess movement and a potential for friction and irritation in the nostrils. Not using heated humidification can dry your nasal passages, dried secretions and cause discomfort. Humidification is highly recommended.
