When mine get blocked I use a chemical called Debrox, or go to the doctor and have them remove it, but there are several ways to unclogged ears.
Do the Valsalva maneuver: This is better known as “popping your ears.” An easy way to do this is to plug your nose and then blow out while keeping your lips closed (it will puff up your cheeks). It’s important not to blow your nose too hard, which could cause problems with your eardrum.
Drip mineral, olive, or baby oil: Warm 2 to 3 tablespoons of your oil of choice, but be careful not to make it too hot. Check it on your hand or wrist to make sure it’s a safe temperature and doesn’t irritate your skin. Then, use an eyedropper to put one to two drops in your ear. Keep your head tilted for 10 to 15 seconds. Do this a couple times daily for up to five days until the blockage seems to be better.
Drip hydrogen peroxide or carbamide peroxide: Combine the peroxide with warm water in a bowl first. Then, follow the steps to apply it as you would for the oil above. You’ll likely experience some fizzing — let it do this and keep your head at an angle until it stops.
Use ear drops: You can pick these up a local pharmacy. Use as directed on the packaging.
Use a nasal spray or oral decongestant: These can be especially useful when flying. They’re often more effective as a preventative treatment. These are available over the counter.
Try ear irrigation: This may help after you’ve made some headway with the blockage. It can be done at home. When the wax is softened, irrigation can help flush it out. For more information, read about ear irrigation.
Use a warm compress or steam: Place a warm compress over your ear or take a hot shower. A shower can help get steam into your ear canal. Just make sure to stay in for at least 5 to 10 minutes.
I hope one of these will help.
