The clinical causes of ear congestion are complex and recovery time cannot be generalized. Ear stuffiness is similar to having a ball of cotton in the ear. Patients speak on their own and feel the sound in their ears, often accompanied by hearing loss and tinnitus. It can be caused by a variety of factors. If the ear is clogged with cerumen, it can usually be relieved by removing the cerumen. In addition, a cold can also cause ear congestion, and the blockage can usually be relieved after the cold has healed in about a week. If a patient has vertigo caused by low-frequency sudden deafness, the stuffy ears may disappear as the vertigo subsides, and treatment with circulation-improving, nerve-nourishing and steroid hormone drugs is recommended. In the case of neurological deafness caused by Meniere’s disease, the deafness can be eliminated or relieved on its own when Meniere’s disease resolves. If a patient experiences ear stuffiness in daily life, he or she should be promptly examined by an otolaryngologist and treated for the cause.
