After two nights of just beginning to use my new CPAP device (I love it so far!), when I removed the nasal pillows this morning, I immediately realized that a cold-sore-like event was on my inner nostril. I presume it stems from a) irritation of something new, b) a reaction to the pillow latex, c) too much moisture (the humidity setting is on on 'auto') from the humidified, d) all or none of the above. I am concerned about using the machine again tonight -- I want to, but am looking for others experiences if it's best to let either breakout and then heal (or just heal, if this is a quick skin event)? Also, I'm interested to hear if others have similar issues upon being introduced to the CPAP device? My supplier suggested I use KY jelly which she said is safe with the pillow latex. Thanks!
