Infectious myringitis is an infection that causes painful blisters
on the eardrum (tympanum).
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.
The main symptom is pain that lasts for 24 - 48 hours. Other symptoms include:
- Draining from the ear
- Hearing loss in the painful ear
Rarely, the hearing loss will continue after the infection has cleared.
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 drugs may be prescribed, as well.
