Dear friend, welcome to Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
It is not possible to puncture the eardrum
with a finger.
It must have been a trivial cut by your nail with the sudden jerk.
It will stop on pressing on the bleeding point firmly with a clean tissue/ sterile gauze.
If should stop with pressure, unless you are on blood thinners like aspirin
or have rare bleeding disorder
If it does not stop with these measures, please see a doctor to know what the problem is.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
