Hi, in my left ear, I ve been having strange pulsing or beating of the ear drum. It is not to the best of my heart- it has an off-and-on spastic rhythm to it. It is very annoying, it makes me cringe and stops me from focusing on my work, but does not cause any pain. Only my left ear. Seems to not happen while yawning, but may happen immediately after... (I am a 17 year old male, with childhood history of a few ear infections) Is this an ear infection? Are there any home remedies that would suffice? How long would this take to clear up on its own, and how long with medication? Thanks!
