I have been affected by ear block quite frequently off late. No it's not due to excess wax accumulation or common cold. I did visit an ENTspecialist recently and was told that this is due to the blockage between ear and nose and should be alright soon and gave me some medicines. I was on medication for 5 days and felt alright for 10 days, now the ear block as reappeared and it's causing too much of inconvenience and lack of concentration at work. The ear block worsens when I am in the air conditioning room. Please help.
