I have pressure in my head. It feels like being under water and ears feel plugged up which affects hearing clearly?

Feeling pressure in your head, along with plugged-up ears and hearing difficulties, could be indicative of several different conditions. Some possible causes include:

1. Sinusitis: This is an inflammation of the sinuses, which are air-filled cavities located around the nose and forehead. When sinuses become inflamed, they can cause pressure and pain around the eyes, forehead, and cheeks, as well as nasal congestion and difficulty hearing.

2. Earwax blockage: A buildup of earwax can obstruct the ear canal and cause a feeling of fullness or pressure in the ear. This can also affect hearing and lead to a muffled or distorted sound quality.

3. Otitis media (middle ear infection): This is an infection of the middle ear, which is located behind the eardrum. It often causes ear pain, fever, and hearing loss, along with a sensation of pressure or fullness in the ear.

4. Eustachian tube dysfunction: The Eustachian tubes are small channels that connect the middle ear to the back of the throat. When these tubes don't function properly, they can cause pressure imbalances in the ear, leading to a feeling of fullness, hearing difficulties, and dizziness.

5. Acoustic neuroma: This is a noncancerous tumor that grows on the nerve connecting the brain to the inner ear. It can cause hearing loss, tinnitus (a ringing or buzzing sound in the ears), and balance problems.

6. Meniere's disease: This is a chronic inner ear disorder that causes episodes of vertigo (a spinning sensation), hearing loss, and a feeling of pressure or fullness in the ear.

7. Migraines: These severe headaches can be accompanied by a variety of symptoms, including head pressure, nausea, sensitivity to light and sound, and hearing disturbances.

8. Head injury: A blow to the head can cause a variety of symptoms, including head pressure, dizziness, hearing difficulties, and memory problems.

If you're experiencing pressure in your head along with ear symptoms, it's important to see a healthcare professional for proper diagnosis and treatment. The doctor may perform various tests, such as an ear exam, hearing test, or imaging studies, to determine the underlying cause of your symptoms. Depending on the diagnosis, treatment options may include medications, earwax removal, or surgical intervention.
