So, it may not seem a natural connection, but your allergies and your hearing aren’t totally unrelated.
The fact is, though we usually take it for granted, our hearing requires an incredibly complicated system to function at a very high level — day in and day out. And yes, allergies can throw sand in the gears.
Allergies usually mean that some part of your body swells. Even if you’re not overly allergic to bees, you’ll have swelling around the sting as the body reacts (and if you have a severe allergic reaction minor swelling is the least of your problems).
With many allergic reactions, there will also be congestion in your chest and nasal cavity. This kind of “clogging up the works” can directly influence your hearing, since this can change the fluid pressure in your inner ear. Your eardrum is calibrated to “normal” pressure and allergy-induced changes will affect the entire system.
Likewise, there are tubes in your middle ear that allow drainage to occur (part of keeping everything calibrated). If those get clogged with fluids produced by an allergic reaction, then things get backed up in the ear canal.
Some allergies will also induce your body to produce more earwax. This just clogs up your ear canal directly. Nothing subtle about that.
Allergic skin reactions can wreak havoc as well, since both your inner and outer ear are, well, covered in skin. If there’s severe swelling in the ear canal the passage is narrowed, which will block sound waves and once again throw off the calibration of the system.
Some things to be aware of if you’re having allergy issues include the urge to scratch inside your ear, bouts of dizziness, and any ringing in your ear. These are all signs that something is amiss.
If there’s a sudden hearing loss, you’ll probably want to have things checked out by a professional.
