What's the pain in the back of the head?

The back of the head shows pressing pain, which may be caused by inflammation, because local subcutaneous lymph nodes are rich, under the premise of suffering from cold or chronic rhinitis, local lymph node enlargement will be shown, and at the same time, the lymph nodes will be compressed and cause local pain. In addition, cardiovascular and cerebrovascular diseases, such as cerebral thrombosis and cerebral arteriosclerosis, can cause similar symptoms, which is due to hypertension or hyperlipidemia, resulting in increased blood viscosity, thus causing damage to the inner wall of blood vessels and thrombosis, causing local compression and tenderness. If hyperlipidemia is poorly controlled, it will cause coronary atherosclerosis, cerebral arteriosclerosis, vasospasm in the later stage, ischemia and hypoxia in the brain, and similar symptoms.
