Various other ear problems can give rise to a sensation of block, for example, inflammation of the ear canal. One should consult an ENT specialist immediately. During common cold, inflammation of the Eustachian tube which connects the throat to the middle ear gives a blocked feeling. As symptoms of cold subside, ear blockage symptoms also go away. Tumors, ulcers or any kind of growth within the ear (as observed during measles) can result in blockage.
