I just got my machine Thursday and when I got up on Friday my ears felt plugged. After a couple of hours it kind of went away. When I got up on Saturday they were plugged up even worse. Is this a side effect of the machine? Has anyone else had this happen? What can I do to stop it? I did not use the machine last night and my ears are still plugged. Please tell me this is not going to happen all of the time. Thank you, Tara
