Why am I having recurring pulsation in right ear which started as a plugged feeling?

Pulsation in the ear with a plugged sensation can have various causes. Some potential reasons for this include:

1. Patulous Eustachian Tube: The Eustachian tube is a small canal that connects the middle ear to the back of the nose. In some cases, the Eustachian tube may become abnormally open or patulous, leading to a pulsatile sensation in the ear. This condition can also cause a feeling of fullness or pressure in the ear and may be accompanied by a popping or clicking sound.

2. Vascular Issues: Pulsation in the ear can sometimes be related to vascular abnormalities or changes in blood flow. This can include conditions such as high blood pressure, arteriosclerosis (hardening of the arteries), or a carotid artery aneurysm (a bulging of the carotid artery in the neck). These conditions can cause an increase in blood flow and pressure in the ear, leading to a pulsation sensation.

3. Muscle Spasms: Spasms or contractions of the muscles in the middle ear can also cause a pulsating sensation. This condition is known as tensor tympani syndrome or myoclonus of the middle ear muscles. It can be caused by various factors, including stress, anxiety, or certain medical conditions.

4. Earwax Blockage: In some cases, pulsation in the ear can be associated with earwax blockage. When excessive earwax accumulates in the ear canal, it can cause a feeling of fullness or plugging and may also lead to pulsatile tinnitus.

5. Glomus Tumor: Glomus tumors are rare, non-cancerous tumors that arise from the small blood vessels in the middle ear. These tumors can cause pulsation in the ear, as well as hearing loss, tinnitus, and aural fullness.

If you are experiencing pulsation in your right ear along with a plugged feeling, it is essential to consult with a healthcare professional, preferably an otolaryngologist (ear, nose, and throat specialist). They can perform a thorough examination of your ear, including an otoscopy (visual examination of the ear) and other tests, to determine the underlying cause of your symptoms and recommend appropriate treatment.
