The so-called “trigger point”, as the name suggests, is a metaphor for the firing of a bullet after pulling the trigger of a pistol, and refers specifically to an area of skeletal muscle that is susceptible to irritation, which is most prone to the occurrence of muscle knots and consequent muscular involvement pain, usually with a compression pain response, and can cause specific point of involvement pain. The “T” in the circle is the trigger point, and the diffuse red dots indicate the extent and degree of pain triggered by the trigger point, with denser red dots indicating more severe pain. Trigeminal neuralgia also has trigger points, which are sensitive trigger points for nerve branches that can trigger muscle spasms and aggravate pain if not touched carefully. Muscle trigger points, on the other hand, are skeletal muscle or myofascial hypertonicity that causes specific pulling pain in a certain area or even a vegetative response. The patient’s main complaint is the location of the red dots, but the most valuable to the doctor is the location of the circle “T”, if you can accurately remember the location of the red dots corresponding to the location of the trigger point, direct use of manipulation to press or stretch the hypertonic areas or damaged muscles to inactivate these active or potential trigger points can quickly relieve or eliminate the pain, and achieve immediate clinical results! This can provide quick relief or elimination of the pain, with immediate clinical results. Remember that not all headaches are caused by intracranial pathology resulting in increased intracranial pressure, hypertension, or cerebral vasodilatation. As shown in the figure, many muscles in the head and neck region that are tense and spastic can form trigger points that can lead to a headache, and can even be difficult to distinguish from a typical migraine headache. Mastery of head and neck muscle lesions caused by various parts of the headache, and targeted warm compresses, passive stretching or deep pressure flick, you can relieve the symptoms of these pain, and even without a doctor to deal with their own home. Also not all upper extremity radiating pain and numbness is caused by cervical spondylosis, clinical very few doctors pay attention to the anterior and middle diagonal muscle tension and spasm can also lead to upper extremity pain and numbness, which also leads to upper extremity pain and numbness for a long time, an important factor, especially to pay attention to. Trigger point is also a good explanation of why some people can get rid of the disease at hand, and some people have treated the soreness into a more serious pain, because the site of the lesion and the site of clinical manifestation is not a complete overlap.
