In this article I found:
“Possible causes of conductive hearing loss include:
- Blockages of the ear canal by impacted earwax (cerumen) or other foreign objects
- Ear infection
- Fluid in the middle ear from a cold or the flu
- Swimmer’s Ear
- ‘Glue Ear’ (middle ear infection, often seen in children)
- Perforated eardrum, from a bad middle ear infection or an accident
- Benign tumours
- Otosclerosis – a hereditary condition where the bone grows around the tiny bones in the middle ear
- A malformation of the outer ear, ear canal or middle ear
- Partial or complete closure of the ear Canal”
in the list of causes. I am pretty amazed, I did not know allergy could cause this. Since I am interested in both issues I Googled it.
“When people think of allergy problems, what comes to mind most often are the classic symptoms of sneezing, runny nose, and itchy eyes. Many people don’t realize that the ears can be affected by allergies, too. Allergies primarily affect the middle ear. the middle ear has a drainage tube or pressure release valve called the eustachian (you-STAY-shun) tube. If this tube is clogged with mucus or its opening is blocked by allergy swelling, then pressure and fluid can build up in the middle ear leading to hearing loss.”
Readin on ZocDoc Answers:
“Yes, the inflammation and extra mucous that allergies cause in your airway are enough to cause fluid to back up in your eustachian tube, which of course leads from the back of your throat all the way to your inner ear. When you have this eustachian tube dysfunction, your hearing will sound muffle, and you just wish that your ears would “pop.””
“Allergy is the term used to describe an over-reaction of the body to a substance that is normally harmless to most people. This substance is called an allergen, and one can be exposed to it in several ways. It may be breathed into the respiratory system, eaten, or touched by the skin to cause symptoms. Often, people inherit a tendency to develop allergies.
SYMPTOMS OF ALLERGY A stuffy nose, runny nose, polyps (growths) in the nose, itching and puffy eyes, frequent sore throats, asthma, skin rashes, and behavioral problems such as hyperactivity in children may be symptoms of allergy. Symptoms may occur in almost all systems of the body, including ears.
Allergy and the Ears Outer Ear symptoms that may be attributed to allergy include chronic itching or frequent infections of the ear canal. Middle Ear symptoms may include repeated ear infections and long-standing fluid behind the eardrum are often due to allergy. Both of these are more common in children. Inner Ear symptoms attributed to allergy may include dizziness, ear fullness and pressure, tinnitus or head noise, and sensorineural (nerve) hearing loss ? especially food allergy. Meniere?s disease in one or both ears may sometimes be aggravated by allergies.”
Clearly if you are allergic and have asthma and you start hearing badly sometimes don’t be afraid. You are not insane. :)
