I have been using a CPAP machine now for a year and a half and have noticed a lot more drainage from my ears than normal. My ears have always had some drainage due to some sinus problems and allergies(however, have never had to take meds for them that much) However, since using the CPAP machine, my right ear,which is the side I sleep on most of the time, drains to the point of stopping up everynight which wakes me up. I have found the lower strap that goes below the ear seems to be putting pressure below my ear to the point of keeping it from draining or causing it to collect and not drain. I wonder if this is a problem with anyone else and if so, what can be done. I am at the point of an ear ache at this time. Besides that, CPAP has changed my life. A lot better sleep and more energy than I have had in years.
