There is a little tinnitus in my left ear

We all know that humans have seven orifices. Generally speaking, these seven orifices are interconnected. If one part is sick and not treated in time, it will cause many other diseases. Some patients often feel a little tinnitus, that is, the ears can always feel a buzzing sound. This sound makes people feel very uncomfortable. So what's the matter with the tinnitus in the left ear? The following is a detailed introduction.

Tinnitus is a sound that the human ear subjectively perceives in the absence of external sound or electrical stimulation. It is worth noting that tinnitus is an illusion occurring in the auditory system. It is a symptom rather than a disease. Some people often feel some special sounds in their ears, such as buzzing, hissing or sharp whistling, but they cannot find the corresponding sound source around. This situation is called tinnitus. Tinnitus makes people upset and restless, and in severe cases it can affect their normal life and work.

Tinnitus can occur in a variety of diseases. Almost any cause of ear disease can lead to tinnitus symptoms, but its relationship with hearing is complex. Tinnitus may be caused by just a small piece of wax touching the eardrum, but it may also be caused by a tumor located on the auditory nerve. Other causes such as otosclerosis (a disease that occurs in the ossicles of the middle ear), ototoxic drug poisoning, noise, etc. can all cause tinnitus to varying degrees. The manifestations of tinnitus vary. Some people have unilateral tinnitus, while others have bilateral tinnitus. Some occur intermittently, while others occur continuously. In mild cases, tinnitus is only felt in quiet times, while in severe cases, the person feels noisy and uneasy even in a busy city.

The main causes of tinnitus are ear diseases, such as external ear diseases: external otitis, cerumen embolism, foreign bodies in the external ear, acute and chronic inflammation of the middle ear, tympanic membrane perforation, otosclerosis and Meniere's syndrome and acoustic neuroma in the inner ear, all of which can cause tinnitus.

Tinnitus can also occur due to vascular diseases, such as glomus jugularis tumor, dilation of small blood vessels in the ear, vascular malformations, hemangiomas, etc. Tinnitus coming from veins is mostly noisy, while tinnitus coming from arteries is consistent with the pulsation of the pulse.
