What is the reason for the cold back of the head?

There are several reasons for the cold in the back of the head: the first may be a feeling before the onset of neuralgia. The second is the symptoms of neurosis caused by anxiety, and there is no pain, but it can also show migratory symptoms. The third is air conditioning, especially after summer air conditioning blows, causing the muscles and nerves in the back of the brain to affect this cold symptom. At the same time, pay attention to whether there is a herpes virus infection in the back of the head. Generally, we can look at the duration of its onset and local symptoms, and if necessary, go to the hospital for relevant examinations to rule out neuralgia, or symptoms of nerve compression caused by cervical spine.
