Scalp pain is caused by many reasons, such as trauma, scalp traction injury, mental factors, and even hypertension. The most common reason is trauma or hair pulling. Women wear ponytails for a long time or recently have hair transplant and other stimuli, which eventually cause head pain. Some patients like to wash their hair at night. If they do not blow dry their hair immediately after washing, the scalp nerve will be damaged. At ordinary times, lack of sleep and mental tension can also cause vascular and neurological pain and reflexively appear scalp pain. If the herpes virus causes local nerve damage, the symptoms of very painful scalp will appear at the initial stage. If the scalp pain cannot be relieved or affects life, you should go to the hospital for inspection and treatment in time to prevent the delay of illness.
