What problems can ear wax cause?
Excessive ear wax can cause hearing loss, pain, and cough. Hearing loss occurs when wax completely blocks the ear canal. This prevents sound waves from easily reaching the ear drum, in exactly the same way that ear plugs (or a strategically-positioned finger) block sound. Even a small amount of wax, if wedged between the ear drum and the ear canal wall, reduces the ability of the ear drum to conduct sound. Some people form very hard wax, which can cause pain by putting pressure on sensitive ear canal walls. Finally, since the ear canal shares some of the same nerves which give sensation to the throat, ear wax can provoke a “tickle in the throat” which can then lead to cough.
