I am experiencing ear ache from past 3 days , i know its due to cold beacuase i am having cold also.. But from past 3-4 months i was feeling blocked ear its not fully blocked but somewhat little blocked , i met an doctor personally he performed several test and an audiograph test ( i don't know correct name ,but the test was of several frequency which was high and low in volume and pitch played in headphones and asked me to put my hands up whenever i hear the note.) The report of the test was normal and doctor said its absolutely fine , but i was still having feeling of somewhat blocked ear , i also performed valsalva maneuver but nothing happened doc. Prescribed medicines and steam i also done that but there was no change ...this problem is in my left ear only AND THE PRESENT PROBLEM is also in left ear..
