Aweek back, I suddenly experienced  deafness  or downing of the sounds from T.V etc.For a moment I thought that the t.V. is not functioning proeprly. But when my daughterin law came near me and asked something ,I only saw her lips mving but nospeech was  heard. From her gestures I could guess that she was inviting me for dinner.  This went on for about 4 hours during which I has a sound sleep,the when I got up I found that I could hear the sounds from the T.V. Next day my family Dr(Ayurvedic ) told me that there was blokage but due to some passage deeloped nside the blockage
