Lying on your side with a thud in your ear may be a normal physiological phenomenon caused by compression of blood vessels in the neck, or it may be a pathological phenomenon such as vascular tinnitus and secretory otitis media.
1. Physiological phenomenon: when lying on the side, the blood vessels around the ear may be compressed, such as superficial temporal artery, facial artery, etc., due to the obstruction of arterial blood flow may be caused by the more pronounced throbbing, the sound of the blood flow may be transmitted to the ear, resulting in the ear has been heard in the thumping sound.
2. Pathological phenomena:
(1) Vascular pulsatile tinnitus: It is a rare type of tinnitus, which is mainly caused by abnormalities in the vascular structure around the ear, resulting in disturbed blood flow, which leads to the formation of abnormal sound conduction to the inner ear. It is mainly characterized by a tinnitus sound that is consistent with the rhythm of the heartbeat or pulse. It can be seen in a variety of diseases such as jugular vein bulboma and tympanic bulboma.
(2) Secretory otitis media: Due to the accumulation of fluid in the tympanic cavity, when lying on the side, the fluid in the tympanic cavity changes its position at the same time, which further stimulates the tympanic membrane due to its gravitational influence, resulting in a thumping sound.
In addition to the above reasons, the ear can also be due to the ear canal cerumen detachment, foreign body in the ear canal, etc. If you change the posture or do not get relief for a long time, it is recommended that you go to the hospital in time to improve the relevant examination, and clarify the cause of the targeted treatment.
