Each morning I would awaken with wet hair from clear liquid draining from my ear. Had CTscan and MRI, but we're unable to determine source. Have not ever experienced problem again since lowering pressure and that was over five years ago.
At pressure of 17 I had a problem with fluid leaking from one of my ears. My ENT, who was also my Sleep Apnea Doctor, had no clue about why my ear was leaking. He sent me to a specialist ENT who was unable to determine the problem. After months of this problem, I had a problem with my APAP, which required me to reboot it. When I rebooted the pressure defaulted to the factory setting. I had no further problem with my ear leaking until several days later, when I realized the setting defaulted. As soon as I changed the setting back to 17 my ear started leaking again. Also had hearing problems that greatly improved at a lower setting. Have since found a new doctor!
