Ear infection? or something seriously wrong?

Your're going to have to wait longer than a few hours. Don't tug on, pull or touch your ears. Silly. The doctor used a suction catheter on you. Your ears must have been in bad shape. No wonder they're sore. For the time being, leave them alone and keep them dry. If you feel no improvement by tomorrow at this time, report this to the ENT. Keep your ears cleaner in the future, dude.
