My ears hurt, what should I do?

Go visit an ear doctor to have it checked up. I have experienced that too especially when I used earplugs to listen to music in my iPod. The music was not loud too. I went to an ear doctor to have my ears checked. I turned out I had ear infection. Until now I have medication for my ears. That's what I can suggest to you.

maybe you have an ear problem and the best solution is for you to have it check up by a doctor specialized in that matter, if the volume is just normal it must have been a co incident that your listening music when you feel the pain

I have felt pain like this in my ears before after listening to music. My ears have also felt like they were still vibrating after listening to music. I think that it is from listening for a long period of time and it being in such close contact to the eardrum. Usually after about thirty minutes of listening to music with earbuds, my ears begin hurting and that is when I know that I have listened to long. I would suggest cutting back on how long you listen for and see if that helps. After listening try finding an activity that doesn't involve continued stimulation of the ear drums, like sitting in a quiet room and reading. Hope that was helpful. Good luck.
