The symptoms you describe still sound primarily like Eustachian tube dysfunction, but could also be caused by fluid in the middle ear cavity, occluding cerumen (ear wax), or a more serious inner ear or auditory nerve disorder. I restate my position that the only way to get an accurate diagnosis and appropriate treatment is to be evaluated by a professional.
Request a tympanogram (or better yet, a complete audiological evaluation). The tympanogram indicates whether the eardrum is moving normally, or if there is abnormal pressure or fluid or other dysfunction. It takes less than a minute per ear and many family Doctors have the equipment, it is just under-utilized. The complete audiological evaluation will indicate just how extensive the hearing is effected and whether it truly is a blockage of sound (conductive hearing loss), or if the problem is within the inner ear or auditory nerve (sensorineural hearing loss), or a combination (mixed hearing loss).
If you have any other symptoms, such as dizziness/vertigo, tinnitus (ringing, humming, hissing or other noises in your ear or head), fever or headaches, make sure you mention that to the Doctor, too. Feel free to contact me if you have any other questions.
