Since it only lasts an hour, could it possibly be migraine activity? I get "nose headaches" which consist of pain spreading from my upper nose, and I am certain these are migraines. If you have a personal or family history of migraine, I would definitely consider that. Migraines are well known to cause facial pressure and ear problems.
But I don't know, it could be something else. Hopefully one of the doctors will be along to answer your question.
Well I can relate... I have had full ears and sinuses for about a year now. It started with an ear infection and now the inner ear fluid is still there. All the doctors do is give me nasonex and Claratin. Im very frustrated, and i get vertigo with it i guess due to the fluid. I am going to try Ear Candeling for the first time and see what that does. Everyone tells me its awsome and will work. Ive tried everything and my blood preasure went up too a tad and i think that is due to anxiety and worry. At least that was my problem. Try the ear candeling see how that works. Usually Herb shops do it.
