To unblock a Eustachian tube, the NHS and medical specialists recommend several gentle maneuvers to equalize ear pressure. The most common is the Valsalva Maneuver: take a deep breath, pinch your nose shut, close your mouth, and gently try to blow air through your nose. You can also try the Toynbee Maneuver, which involves pinching your nose and swallowing at the same time. Other simple remedies include yawning widely, chewing gum, or using a "popping" device like an Otovent balloon. If the blockage is due to allergies, the NHS suggests using a decongestant nasal spray or antihistamines to reduce inflammation. If symptoms like "muffled hearing" or pain persist for more than two weeks, you should see a GP, as chronic Eustachian Tube Dysfunction (ETD) might require a minor procedure like balloon dilation or the insertion of ear grommets (tubes).
