Summarize this article in one sentence.
Blockage by earwax or other debris is a common cause of CHL. Earwax is healthy in small amounts and has protective, lubricating and antibacterial properties. Most of the time the ear canals are self-cleaning, but sometimes they become clogged or impacted, which causes partial hearing loss in addition to sensations of ear fullness, itchiness or ringing (tinnitus). Cotton-tipped applicators are not recommended for cleaning deep into the ear canal, so consider safer methods such as placing a few drops of mineral oil, baby oil or glycerin into your clogged ear.  Hydrogen peroxide or carbamide peroxide drops may also safely dissolve earwax, although they will likely cause a benign stinging or burning sensation for a few minutes. Irrigation or ear syringing can be performed by a physician or at home using widely available and inexpensive irrigation kits. Make sure to use a warm saline solution for best results. A procedure called ear candling is not recommended by doctors to clean ear canals due to risks of burning and eardrum perforation. The common cold, sinusitis and allergies can clog the eustachian tubes (which connect the middle ear with the upper throat and nasal cavity) with fluid and mucous, leading to ear pain, popping sensations and reduced hearing. Blocked eustachian tubes often get better without attention, but to accelerate their clearing try closing your mouth and holding your nose, then gently blow as if you are blowing your nose.  Yawning or chewing gum also may help unclog eustachian tubes. You may feel a "pop" when the tubes open up, which signifies equal pressure between the inside and outside of your ears. Antibiotics destroy or inhibit the growth of microorganisms such as the pathogenic bacteria that can cause inner and middle ear infections. If your doctor diagnoses you with an ear infection, then an antibiotic such as amoxicillin might be helpful and help restore your hearing. Keep in mind that some oral antibiotics, such as erythromycin and tetracycline, can also cause hearing loss.

Summary:
Clean out your outer ear canal. Clear out your eustachian tubes. Consider the use of antibiotics.
