It possible that you may have ruptured your ear drum.
I think it would be best if you are evaluated by your doctor so the cause of the rupture can be determined. If it is from a middle ear infection (even though your ear doesn't hurt right now) then antibiotics will be needed if it is from bacteria.
Is this something that you need to go to the emergency room for? From what you have told me, no. That being said the sooner your doctor can have a look in your ear the better.
Until you see you doctor you can use cold compresses to help with the external itching.
Does this make sense to you?
