Long term sufferer from a clogged ear here. I’ll explain why later on. Stop attempting to use something directly in your ear, like a cotton swab or any form of liquid. It is more likely to cause more harm than good. A heat source may help, but it never did for me. Avoid using an “ear candle”. There is no proof that they work. Most doctors report that they are ineffective and can actually cause more harm.
It could just be an ear infection. If that is the case, you can either let it run its course and suffer through it or go to a doctor and get a prescription for an antibiotic.
If you aren’t willing to do either, then try an over-the-counter decongestant or antihistamine. Either will help dry up the fluid build-up in the sinus and ear canals.
Have you recently been exposed to an increase in high and low altitudes? This is how I discovered that the inner pain I was suffering from came on. It took seeing several different doctors before one told me that there was scarring in the Eustachian tube that probably occurred as a baby. The scarring narrowed the tube and was more susceptible to fluid build-up. A recent job change had me taking several connecting flights, plus driving up and down mountainous regions on a weekly basis. Taking a decongestant daily for a few days helped dry up the fluid.
Your best bet is to make an appt. with a doctor. Hearing loss is not worth second-guessing and attempting to self-medicate if left untreated by a professional.
