The headache is not a big problem, but the pain is really deadly. This is not, Xiao Zhou headache old problem again. The right side of his head was throbbing with pain, making him feel nauseous and want to vomit, and he couldn’t sleep or eat well all day, so he couldn’t concentrate on his work. He went to the hospital for a checkup, but no organic lesions were found and he was diagnosed with migraine. The doctor told him that he could only take anti-inflammatory painkillers to relieve the symptoms, and there was no special medicine to break the root of the disease. Xiao Zhou used to live on these pills, but this time the drugs did not work. He was in pain for several days when he suddenly remembered that someone had suggested he try hyperbaric oxygen therapy. At that time, he did not know what hyperbaric oxygen was, and did not believe that it would work, but he had no choice but to try it in the heat of the moment. Zhou took a chance and came to the hyperbaric oxygen department and saw a large chamber shaped like a submarine. The oxygen chamber doctor told him to sit in the chamber and put on a mask to inhale oxygen, a very simple treatment process. After an hour or so, Zhou felt refreshed and invigorated, and his headache was relieved, changing the way he looked before treatment. How come he didn’t come to inhale oxygen earlier, Zhou cursed himself. He was curious about hyperbaric oxygen and asked his doctor for advice. The doctor told him: hyperbaric oxygen therapy is to let the patient suck pure oxygen in a higher than normal pressure environment. Now the general treatment pressure is 2 atmospheres. The oxygen content in the blood increases significantly when the patient inhales hyperbaric oxygen, and the diffusion range of oxygen expands, which enables more tissue cells to absorb oxygen. Nowadays, many office workers often suffer from fatigue and drowsiness, which is a manifestation of excessive energy consumption and lack of oxygen in the organism, and hyperbaric oxygen therapy can relieve such symptoms very quickly. The causes of migraine are still being explored, but current research has found that the defective analgesic function of the central nervous system and the dilation of blood vessels in the head can cause migraine. Hyperbaric oxygen therapy can reduce platelet coagulation and inhibit the release of 5-HT from platelets, thus promoting vasoconstriction in the head; it can also lower intracranial pressure, reduce brain tissue edema, prevent cerebral vascular spasm, promote brain metabolism and regulate autonomic function. Hyperbaric oxygen not only effectively relieves the symptoms of migraine, but also prevents the frequent attacks of migraine and reduces the degree of attacks. Xiao Zhou was one of the lucky ones who had a very significant effect. Accordingly, the doctor gave Xiao Zhou a “small prescription for oxygen therapy”: 20 times of hyperbaric oxygen treatment, and 10-20 times of consolidation treatment after six months to prevent recurrence.
