I do not feel sick or anything, but there is a constant drumming going on inside my left ear. It sounds like continuos drum beating. I can stop it for a second by trying to pop my ears like on a plane. I took some flonase in case it is allergy related. I am not congested or anything, but this noise is driving me crazy! If I touch my finger to my outter ear and apply pressure, it stops. What can I do?
