Hi, I am facing some kind of blockage in my left ear and when i hear any sound it seems that it is Not coming cleraly, i showed to ent specialist and she gave some medicine lile quicknac, pcare dsr,desthama 30mg and one nasal spray, she told if fluid does not come out there needs to be some small surgery to take the fluid out. Surprisingly i didn't have any cold or fever or dont remember blowing out my nouse harshly which may have been the cause of my nasal fluid going into ears. Any suggestions please?
