Sub aqua divers and airline pilots clear their ears (equalize the pressures) by performing the Valsalva maneuver (see the link below). To do this you hold your nose, close your mouth and gently 'blow out' your ears. This should clear your ears unless you have a bad cold or an allergy which is blocking your eustachian tubes, in which case you will have to wait for them to gradually equalise on their own.
The Eustachian tubes
Yes, allergies can cause blocked Eustachian tubes. When the body reacts to allergens, it can lead to inflammation and swelling in the nasal passages and throat, which may extend to the Eustachian tubes. This blockage can result in symptoms such as ear pressure, discomfort, and difficulty hearing. Managing allergies effectively can help alleviate these symptoms and promote proper Eustachian tube function.
The Eustachian tube connects the middle ear to the throat. Its main function is to help equalize air pressure on both sides of the eardrum, which is important for proper hearing and balance. If the Eustachian tube is blocked or dysfunctional, it can lead to ear pain and hearing problems.

Those are called the Eustachian tubes.
Nasopharynx
Eustachian tubes
The eustachian tubes are the auditory tubes that link the nasopharynx to the middle ear.
Ear tubes or grommets, are used in children to help alleviate persistent infections caused by a blockage in the Eustachian tubes. These blockages can be caused by large adenoids, or blocked nose/sinuses caused by viral infections or allergies.
Eustachian tubes are part of our auditory system their function is to equalize pressure on both sides of our ear drum so that it can vibrate freely.
Salpingostenosis is the medical term meaning abnormal narrowing of the eustachian tube. The breakdown is salpingo- (tube - usually eustachian or fallopian) and -stenosis (abnormal narrowing).
