Does a bleeding ear always mean you ruptured your eardrum ?

Sounds like you have a handle on what happened. I would suggest you try cleaning your ears every month or so with an ear cleaner like Debrox. Or you can mix equal parts of hydrogen peroxide, vinegar, and alcohol. This mix is also very good for swimmer's ear and long earred dogs.( I had a basset and a cocker spaniel.) If a person does not have the wax build up, or for cats, leave out the peroxide. Another thought, sometimes you can get a pimple inside the ear canal that can open up and bleed. Get your mom or dad to look in and see what they can see.
