Are you having cough? Sometimes, mucous builds up behind the ear drum which may cause temporary deafness due to obstruction. If your hearing problem is due to mucous, then you must include plenty of garlic, onions, chillies and peppers to thin down mucous. Having a bowl of soup with crushed black pepper may help relieve mucous formation. If deafness is due to build up of plaque in tiny blood vessels that supply blood to the ears, then reducing intake of fats especially saturated fats like butter, margarine, ghee, milk fat, red meat will be helpful. Hope this answers your query.
