okay so I'm not sure if this is tinnitus or not, but I just woke up from a nap and am now experiencing a faint echo like noise in my left ear.. I can hear fine but whenever I talk mostly or someone else it sounds like faintly robotic or like if someone were to stand in front of a fan and talk, echo.. Not sure what this is but it's quite annoying.. Anyone know how to get rid of this or what it could be? Thanks!
