Hello and thank you for your question! Pressure in ear may be caused by various factors.This type of discomfort in the ear is due to pressure differences between the inside and outside of the eardrum. Failure to effectively regulate air pressure results from a blocked, swollen, or collapsed Eustachian tube. Air and fluid become trapped causing a buildup of pressure in the middle ear. The problem often occurs with altitude changes, (flying, scuba diving) or when you have a congested nose from allergies, colds, or an upper respiratory infection.Ear infections, and respiratory infections, involving the sinuses, nose, and throat, all cause blockage of the Eustachian tube, resulting in increased pressure in ear. To relieve ear pain or discomfort, you can take steps to open the Eustachian tube and relieve the pressure, such as: Inhale, and then gently exhale while holding the nostrils closed and the mouth shut, Yawn, Taking an over the counter decongestant.If ear pressure persists or the condition worsens, a search for the underlying cause is warranted. Conditions to watch out for include drainage or bleeding from the ear, fever, or severe ear pain. In this cases you must go the otorhinolaryngologist because you might need to take some medicines : antibiotic, antihistamine, decongestant or steroid . Best regards!
