Feeling of Ear Congestion and Muffled Hearing: Is It Normal?

The ear feels like there is a membrane blocking it, making it difficult to hear clearly?

Hello, I recently had otitis externa, and my doctor prescribed me ear drops containing dexamethasone.
During my last visit, she mentioned that I should continue using them for another 5 days.
However, last night (February 24, 2020), when I administered the last dose, I felt a sensation of fullness in my ear, as if there was a membrane blocking it.
I didn't think much of it and went to sleep.
To my surprise, when I woke up today, I still felt that fullness in my ear and had difficulty hearing clearly.
By the afternoon, I even started experiencing tinnitus.
Is this normal? Thank you!

Hello, a common sensation of having a membrane in the ear that makes it difficult to hear clearly may be related to swelling of the external auditory canal or the presence of secretions or earwax within the canal.
If discomfort persists after using the medication, please return for a follow-up examination to determine if local treatment is necessary.
Wishing you safety and health, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

The sensation of ear congestion and muffled hearing can be concerning, especially after experiencing external ear inflammation and using ear drops. Based on your description, it seems that you are experiencing a common phenomenon that can occur after ear infections or inflammation, but it is essential to understand the underlying mechanisms and when to seek further medical attention.

When you have an ear infection or inflammation, such as external otitis (commonly known as swimmer's ear), the ear canal can become swollen and filled with fluid. This can lead to a sensation of fullness or pressure in the ear, often described as feeling like there is a "layer" or "membrane" blocking sound. This sensation can also be accompanied by muffled hearing, as the sound waves have a harder time traveling through the swollen or fluid-filled ear canal.

The use of ear drops, such as the one you mentioned (likely a combination of an antibiotic and a steroid), is intended to reduce inflammation and treat any infection. However, if the ear canal is still swollen or if there is residual fluid, you may continue to experience these symptoms even after completing the treatment. The presence of earwax can also contribute to a feeling of fullness and muffled hearing, especially if it has been pushed deeper into the ear canal during the application of ear drops.

The onset of tinnitus (ringing or buzzing in the ear) that you mentioned could be related to the same underlying issues. Tinnitus can occur due to various reasons, including changes in ear pressure, inflammation, or even as a side effect of certain medications. It is not uncommon for individuals recovering from ear infections to experience temporary tinnitus as the ear heals.

In most cases, if the sensation of fullness and muffled hearing persists for more than a few days after completing treatment, or if it worsens, it is advisable to follow up with your healthcare provider or an ear, nose, and throat (ENT) specialist. They can perform a thorough examination of your ear, including checking for any remaining fluid, wax buildup, or other issues that may need to be addressed.
It's also important to note that if you experience additional symptoms such as severe pain, fever, or drainage from the ear, you should seek medical attention promptly, as these could indicate a more serious infection or complication.

In summary, while the feelings of ear congestion and muffled hearing can be normal following an ear infection, especially after treatment, it is crucial to monitor your symptoms. If they do not improve or if you have any concerns, do not hesitate to consult with a healthcare professional for further evaluation and management. Your ear health is important, and timely intervention can help prevent potential complications.
