Body temperature of 37.5 ℃, generalized soreness is caused by excessive accumulation of lactic acid in the muscles, due to viral and bacterial stimulation of the nerves, the pyrogen can cause an increase in the production of inflammatory factors in the body, the nutrient metabolism of intra-muscular cells is blocked to a certain extent, the cells do not get enough oxygen supply, the pyrogens act on the center of thermoregulation, motor nerve impulses, so that the whole body of the skeletal muscle spasms, and at the same time, the body temperature increases, the basal metabolism increases, causing the accumulation of lactic acid in the muscle. At the same time, the body temperature rises, the basic metabolism increases, causing the accumulation of lactic acid in the muscle, muscle pain and other symptoms. Such symptoms can be relieved by taking antipyretic and analgesic drugs, such as ibuprofen, acetaminophen and other drugs to improve and cool down the temperature, and it is necessary to have sufficient rest and avoid strenuous exercise.
