The eardrum is also known as the tympanic membrane. If you feel that the tympanic membrane is swollen and uncomfortable, consider that the tympanic chamber is filled with fluid caused by secretory otitis media. If the tympanic membrane is swollen due to fluid accumulation in the tympanic chamber, tympanic membrane perforation and fluid extraction treatment is feasible. If it is a recurrent case of secretory otitis media, tympanic membrane placement surgery is required and the cause of secretory otitis media should be clarified and treated in order to completely solve the problem of ear swelling. If the eustachian tube is blocked due to malfunction of the eustachian tube, it can also cause a feeling of swelling of the eardrum. If the obstruction is caused by the eustachian tube, in the absence of nasal congestion or nasal discharge, the eustachian tube can be blown open by pinching and puffing, or the tympanic membrane can be relieved by pressing on the ear screen. You should not pull out your ears by yourself or let others pull out your ears to avoid damaging the eardrum and causing deafness.
