 | | Your symptom (''profound hearing loss'') is a bit vague, an audiogram (hearing test) should have been performed in order to determine whether the hearing loss was coming from the outer, middle or inner ear. |
 | | This may cause a sensorineural hearing loss, in association with a sensation of fullness, pressure and often vertigo. |
 | | However, without a proper audiogram, all of this is speculation, as sudden hearing loss may be caused by viral infection, tumor, multiple sclerosis, stroke and chronic ear infections. |
