Most patients with pain symptoms generally do not have a good understanding of the cause of their pain and are unable to go to the hospital in the first place, delaying the best time for treatment and making the condition more difficult to treat by dragging it to the middle and late stages. Timely diagnosis of whether pain is normal or not is one of the key steps to relieve symptoms and reduce pain. So how should the pain be diagnosed when it is severe, the following is a detailed introduction. 1.Interrogation Ask questions to understand the occurrence, development and medical treatment of the disease, and to understand the symptoms, signs and problems of the disease now. Listen carefully to the patient’s complaints, and understand the most painful and obvious main feelings and the reasons and purposes for seeking medical treatment. After listening to the patient’s complaint, we should further understand the history of the disease and clarify the entire process from the onset and development of the disease to the time of seeking medical attention. 2, palpation With the thumb of one hand or both thumbs, along the longitudinal axis of muscle fibers and tendons, carefully touch the degree of soft tissue injury, the extent and depth of pressure points. When palpating the spine, press the thumbs of both hands against both sides of the spinal column and check the spinous process for deviation and the supraspinous and interspinous ligaments for rupture or curl in order from top to bottom. In the joint areas of the extremities, the degree of soft tissue injury and the effect on joint function should be palpated along the joint space. In the nervous system, attention should be paid to the state of consciousness, warmth and pain sensation, touch, position sensation, deep and superficial reflexes, spinal cord innervation areas, and determination of the location of the horizontal plane of damage.
