The head is throbbing with pain, which is actually neuralgia. The characteristic of neuralgia in the head is like this, the pain stops after a few times, the interval may be different, there are short and long, and then it starts again in a while, repeatedly like this, and the pain will be like electric needles. Neuralgia is commonly found in: 1) the posterior occipital region, i.e., the head behind the ear, called occipital neuralgia; 2) the orbit and upper forehead, called supraorbital neuralgia, which are the two most common places for head and facial neuralgia. If the scalp hurts all at once, it also belongs to neuralgia, but this is basically the cervical nerve, which is an irritation of the nerve roots of neck 1, neck 2 and neck 3.
