Earwax, also called cerumen, is made by the body to protect the ears. The ear wax has both lubricating and antibacterial properties. Ears are designed to clean themselves. Earwax buildup and blockage often happens when people use items like cotton swabs or bobby pins to try to clean their ears. This only pushes the earwax farther into the ears and can also cause injury to the ear.  Most of the time, the old earwax is moved through the ear canal by jaw motions like chewing while the skin in your ear grows from the inside out. When it reaches the outside of the ear, it flakes off.
If left untreated, excessive earwax may cause symptoms of earwax blockage to become worse. These symptoms might include: - sudden or partial hearing loss, which is usually temporary, tinnitus, which is a ringing or buzzing in the ear, a feeling of fullness in the ear, earache.  A buildup of earwax might also make it difficult to see into the ear, which may result in potential problems going undiagnosed.
Healthy earwax comes in a range of colors. There is 2 types of ear wax - wet earwax or dry earwax. Wet earwax comes in a range of colors including light yellow, honey-color, and orange-brown. Wet earwax is sticky. Dry earwax is likely to be whitish or gray in color and is flaky.
If your earwax is more of a discharge, like it contains white or greenish pus, or you find it caked on your pillow after sleeping, you should contact doctor.
