Infectious myringitis is an infection that causes painful blisters on the eardrum (tympanic membrane).
Infectious myringitis is caused by the same viruses or bacteria that cause middle ear infections. The most common of these is mycoplasma. It is often found along with the common cold or other similar infections.
The condition is most often seen in children, but it may also occur in adults.
Exams and Tests
The health care provider will do an exam of your ear to look for blisters on the ear drum.
Infectious myringitis is usually treated with antibiotics. These may be given by mouth or as drops in the ear. If the pain is severe, small cuts may be made in the blisters so they can drain. Pain-killing medicines may be prescribed, as well.
