Why does earwax sometimes block the ear canal?
When a patient has wax blocked up against the eardrum, it is often because he has been probing his ear with such things as cotton-tipped applicators, bobby pins or twisted napkin corners. Such objects only serve as ramrods to push the wax in deeper. Also, the skin of the ear canal and the eardrum is very thin and fragile and is easily injured. Continual rubbing of the ear canal with a cotton-tipped applicator can abrade the skin and promote an infection.
