A cool sensation in the back of the head may be a sign that the localized nerves in the back of the head, such as the occipital nerve, have been damaged due to viral infections, ischemia, and other reasons. It may also be a manifestation of nerve dysfunction.
1. A cool sensation in the back of the head indicates that the local sensory nerves are functioning abnormally. This may be because the occipital nerve and other nerves in the back of the head are infected by a virus when the immune system is low, resulting in abnormal function of these nerves, coldness, numbness, pain and other abnormal sensations.
2. If the blood supply to these nerves is affected by trauma, localized muscle spasms, cervical spondylosis, etc., similar manifestations may also occur.
3. When a person is overworked, stressed, or stays up all night, he or she will experience nerve dysfunction, and may then experience a cool sensation at the back of the head. However, this is only a transient functional abnormality, not a disease, in the appropriate rest, relaxation, will generally return to normal.
If the symptoms persist, and even with other manifestations such as headache, you need to go to the hospital to improve the head CT and other tests, by the doctor to diagnose the cause of the disease in person, and give targeted treatment.
