Tightness of the scalp is mainly associated with neurasthenia, incorrect posture and nervous headaches, and bloodletting is not recommended during episodes of illness. Scalp tightness is an abnormal manifestation of the head and is associated with three main diseases. The first is a long-term state of high pressure or anxiety state caused by neurasthenia, followed by a long period of time to play with the phone or sit in an incorrect posture caused by the muscles in a state of continuous contraction or neurological headache attacks can also lead to scalp tightness. All these three diseases are closely related to muscles or nerves and are not recommended to be treated with bloodletting therapy. Bloodletting therapy is mainly indicated for solid, hot or painful types of disorders. Bloodletting during an attack of scalp tightness will not relieve or may even worsen the head pain because the blood supply to the brain is affected. Bloodletting is less effective when scalp tightness occurs and it is recommended to take pain medication or exercise rehabilitation depending on the situation. Patients need to go to the hospital as soon as possible to find out the cause of the disease and have the relevant treatment according to the cause of the disease.
