Infectious myringitis is a contagious disease that causes painful blisters on the eardrum (tympanum). It may occur with a middle ear infection (otitis media).

Causes

Infectious myringitis is a viral or bacterial infection. It is usually a complication of a common cold virus. Rarely, it may be caused by an infection with mycoplasma pneumonia.

Symptoms

The main symptom is pain that lasts for 24 - 48 hours. Other symptoms include draining from the ear and hearing loss in the painful ear. Rarely, the hearing loss will continue after the infection has cleared.

Treatment

Infectious myringitis is usually treated with antibiotics, either given as drops in the ear or by mouth. If the pain is severe, the blisters may be lanced and pain-killing drugs may be prescribed.

Alternative Names

Bullous myringitis
