Reply to Ear Pain

In my left ear. I don't hear any ringing sounds, so I don't believe that it is tinnitus. With regards to listening to music: I don't DJ in clubs, I only listen to music at home, for both leisure and DJing purposes, quietly and never usually for extreme periods of time. It's been happening all day, feels like my left ear is congested - sort of like when you're on a plane - and when I go to listen to music on my laptop, without headphones, it starts annoying me really fast so I turn it off.

Infection?
