My Ears feel numb and weird after loud music?

I was sleeping and listening to music and the sound level was at like 4 bubbles on the iphone then my friend played a prank on me and raised it to full volume suddenly when I was sleeping. I didn't wake up until few minutes have passed. After, my left ear felt so weird as if I was in an air plane. I don't have any problem hearing, but the sensation is weird because it feels numb to the back of my head.

It goes away then comes back. It usually lasts 1-2 hrs and when I wake up at night I have that sensation.

It's been going on for 2 days now: L

Did I damage my hearing? Also, I usually listen to loud music at half full and listen 4-8hrs a day.

I think that usually extreme volume oscilations can damage more the hearing than just hearing loud music, if you were hearing more than 25dbs with headphones yhea maybe your hearing have been damaged, here is my advice take a rest of 15 min after every hour you listen to music. If you want just try one day without music and away of loud and crazy noises, if nothing of that works just go to the doctor man.
