I have chronic clogged ears, went to ENT nothing even got tested for allergies and nothing, and cat scan. Dont know what to do?

Blocked ears. Sometimes we can't find a cause for this problem; we have two aerosol nasal sprays that can be tried.The aerosols often get back through the nasal passages to the eustachian tube openings that connect to the throat better than aqueous sprays. They are called zetonna and qnasl. Some of my patients also find it helpful to take sudafed on the mornings they are blocked. Try a milk free diet too.
