Damage to nerve endings may occur due to inflammation or cardiovascular disease, such as hypertension, diabetes, or hyperlipidemia. After infection with bacteria or viruses, the inflammation in the body expands and affects the security of the peripheral nerves causing nerve damage, which can clinically lead to reduced nerve sensitivity. Diabetic hyperlipidemia can lead to lesions in the tiny blood vessels in the peripheral circulation of the body, which can lead to thrombosis and damage to peripheral nerves. In chronic cervical spondylosis, the nerve endings of the nerve are damaged due to compression of the nerve root by the herniated disc. In addition, anemia or deficiency of vitamins and other trace elements can cause similar phenomena, which need to be examined in time.
