Ruptured eardrum :
The ruptured eardrum usually refers to the presence of a hole in the eardrum and feels like a sharp pain in the ear, affecting the hearing and sense of balance. A ruptured eardrum can cause long-term hearing loss, long-term vertigo, long-term dizziness, persistent ear drum perforation, and infection that can spread in the ear. The common signs of a ruptured eardrum are sudden hearing loss, sudden sharp pain in the ear, drainage from the ear that looks like pus or blood, and buzzing noise in the ear coming from outside of the ears. A ruptured eardrum is caused by the use of cotton swabs or other small pointed objects to scratch or clean the ears, trauma to the ear, barotrauma if the eustachian tube is irritated, and sudden explosive sounds. The ruptured eardrum, in some cases, heals on its own and may also need treatments like myringoplasty and tympanoplasty in few circumstances.
