I am having "crackling" and "popping" in my left ear, and it sounds as if someone is blowing in the ear. A hearing test was normal for my age. An MRI was normal. An ear Dr. removed a large white plug with some red streaks from the ear, but it did not change the sounds. Ibuprofen 3 times a day for two weeks did not help. Sometimes I'm only aware of it when it's quiet, but lately it's so loud I can hear and feel it constantly. It's not painful, but it's not pleasant. Any suggestions?
