The head shakes as if there is a sound inside consider arteriosclerosis cerebral tinnitus, cerumen, neck strain and other causes.
When cerebral arteriosclerosis causes the elasticity of the blood vessel wall to weaken when the blood flow impacts the blood vessel wall can cause cerebral tinnitus symptoms to occur. The sound may include buzzing, running water, bird song or insect chirping. The sound is noticeable when the head is shaking, at night, or when the surroundings are quiet. Further cerebrovascular imaging (e.g., head and neck CTA or head and neck MRA) may be performed to exclude conditions such as stenosis and vascular malformations.
A fine rustling sound may occur when turning the head when fine cerumen is present in the ear.
The sound when turning the head when the cervical spine is moving is caused by the prolonged strain of the neck in a short period of time, such as long-term low head posture, lack of activity and exercise, late night labor, etc., which causes the muscles and ligaments of the neck to be in a spasmodic state, and the articular cartilages and ligaments in the neck rub against each other when the head is turned, which will lead to the appearance of a rasping sound.
The symptoms of head shaking as if there is a sound inside, it is recommended that patients seek early medical attention, improve the relevant examination to clarify the diagnosis, timely treatment, so as not to delay the condition.
