the bodies membranes are fickle bitches, and the tympanic membrane is the smallest and most taught of them all. They can heal and regenerate. Perforations that result from infections, as when a tympanic membrane bursts, or when chronic infections have led to irreparable damage to the membrane itself, often do not heal. But if you just poked a hole in it with a Q tip or by some other trauma, your chances are better.
So the question is HOW did you pop your drum, man?
also, bleeding from the ear needs medical attention period. With pain, no pain, headache, lightheadedness, euforia, etc etc, doesn't matter, all bad. Blood in the ear is a big ol "check engine" light for your head.
