Features: This book is a comprehensive introduction to headaches. Headache is a very common symptom, which is the subjective sensation produced by the body in response to various pain-inducing factors and falls under the category of pain. The pain-inducing factors can be physical, chemical, biochemical, or mechanical. These factors stimulate sensory nerve endings located in the tissues and structures inside and outside the cranium, which then transmit signals through corresponding pathways to the brain, where the sensation is perceived. Like other types of pain, headaches not only have a physical sensory component but are often accompanied by emotional responses. Due to the varying distribution of pain-sensing nerve endings within the cranial cavity and different tissues, the same stimulus may elicit different levels of sensitivity in different tissues. Additionally, since individual pain tolerance varies, the response to pain can also differ significantly.
