Whiplash headache (syndrome) is often caused when an external force acts on a part of the body to accelerate its movement, while the head is still in a relatively static state, resulting in whip-like action, causing neck over-extension and over-flexion (or vice versa), resulting in injury at the craniocervical junction (or even neck and shoulder) most often, which is divided into several types according to the main parts of the injury, causing different clinical manifestations: 1, cervical spine contusion type (cervical soft tissue injury type ) mainly manifested as head and neck muscles persistent dull pain, accompanied by local pressure pain and cervical muscle stiffness. 2.Nerve root type has obvious sensory disorder and radiating pain consistent with nerve distribution. The pain is persistent or paroxysmal cutting-like pain, which is an irritation symptom of the related nerve root. 3.Vertebrobasilar type Headache, dizziness, tinnitus, swelling of both eyes, foggy vision, eye fatigue, and sometimes episodes of transient vertigo (visual rotation) are caused by the involvement of vertebrobasilar artery. 4. Sympathetic symptoms include nausea, lacrimation, excessive sweating, facial flushing, conjunctival congestion and palpitations, which are due to sympathetic nerve involvement in the posterior cervical region. 5. The spinal cord type is caused by cervical spinal bone precipitation or vertebral joint slippage resulting in cervical medullary compression symptoms, mainly manifesting as lower limb motor and sensory impairment, abnormal tendon reflexes, etc. This type and the nerve root type are less common in pain or headache and dizziness departments. It is worth pointing out that: First, the symptoms of the above-mentioned types often do not appear immediately after the injury or only have dizziness, headache, and transient impairment of consciousness. With the prolongation of time, the injury causes continuous spasm and ischemia of the muscles of the neck and even the back of the shoulder, resulting in a variety of symptoms. Second, the above-mentioned types rarely exist independently in clinical practice, and most patients are a mixture of two or even three types. Most patients have a mixture of two or even three types. Type 1, 3, and 4 are more common, so mixed symptoms occur more often. Third, such patients generally have a history of injury in a relatively special state (such as the patient Xiaohu in this paper) and a series of corresponding symptoms, this special history of trauma must be told to the doctor, is an important clue to the doctor’s examination and diagnosis. About treatment After the diagnosis is initially determined based on the medical history and clinical examination (and relevant auxiliary examinations if necessary), the preferred effective treatment is to perform a local nerve block (closure therapy), which can often achieve immediate results. In this paper, the case of Xiaohugen complained of symptoms and examination is a mixture of 1, 3, type, the examination found that the occipital and posterior cervical pressure pain, but to the circumoccipital junction area and 2 cm below the occipital ridge (supraoccipital margin) pressure pain is the most significant, so selected for closure point, after the injection of liquid, the patient immediately felt the above head and eye symptoms reduced by half, and then supplemented with sedation, analgesia and muscle relaxants and vasodilators, such as Valium, Fenbid; prednisone Prednisone or Myna; 654-2 and other general treatment. (If necessary, add 40-60ml of salvia to 300ml of low-molecular dextrose or 5% glucose solution, and inject intravenously once a day for 7-10 times, for better effect.) Local nerve block therapy once a week, usually 2~3 times, individual patients can achieve the expected effect with 5 times. Note: Local nerve block (closed therapy) solution: the author used: 2% lidocaine 7.5 ml, methylprednisolone 20 mg ~ 40 mg, scopolamine 5 mg total three kinds of mixture about 4 ml.
