Ear discharge, also known as otorrhea, is formed by any fluid that comes from the ear. Usually, the ears discharge earwax, a protective oil that the body produces naturally. But other conditions or injuries to the eardrum can cause blood or other fluids to drain from the ear. This type of discharge is a sign that the ear has been injured or infected and requires medical attention.
Causes of discharge from the ear
In most cases, the discharge from the ear is wax, but other reasons, such as infection or injury, should not be ruled out. Middle ear infections, for example, are a common cause discharge from the ear. This occurs when bacteria or viruses lodge there.
With middle ear infections, fluid builds up behind the eardrum, and if there is too much, there is a risk of perforation of the eardrum, inevitably leading to discharge from the ear. The middle ear contains three bones called ossicles., which are essential for hearing and which will also be affected by the infection.
Trauma to the ear canal can also cause discharge. Also it is common for cotton swabs to cause discharge, if you push them too deep.
Other causes of symptoms in the ear can be:
- Increased pressure, such as that experienced when flying in an airplane or when diving, can result in trauma to the ear.
- Acoustic trauma, hearing damage due to extremely loud noises. Acoustic trauma can cause the eardrum to rupture, however these cases are not as common.
- Otitis externa (swimmer’s ear), What happens when a bacteria or fungus infects the ear canal. It usually occurs when you spend long periods of time in the water.
A less common cause of discharge from the ear is malignant otitis externa, a complication of infection It causes damage to the cartilage and bones at the base of the skull.
In most cases, an ear rash is not a cause for alarm, however, if they are recurrent or are accompanied by bleeding, a doctor should be consulted.
Piercing makes the ear susceptible to infection. It is very important to keep the area clean at all times, to avoid worsening symptoms.
Another type of rash is eczema, a skin disorder It can appear anywhere on the body, including the ear.
