I am a 35 year old male (very healthy) however for the last two weeks I have had a muffled feeling in my ears....i hear it more when there are bass type sounds (like low voices). when I wake up in the morning it sounds kind of like wind is blowing in my ears. I just went to the doctor and he didn't see anything too concerning in my ears, thought it might be due to allergies so he told me to take sudafed but after taking it twice I haven't noticed any difference?
