Cold and flu are mostly viral infections, but can also be combined with bacterial invasion, the pathogenic bacteria will release a variety of substances, which can lead to generalized aches and pains. At the same time, the wind-cold cold after the whole body vasoconstriction, local blood stagnation, causing muscle, fascia, bone and joint pain. The human body is in a relatively stable state, long-term late night, malnutrition, overwork, etc. can body immunity decline, plant nervous system dysfunction. At this time, viruses and bacteria will take advantage of the situation, causing the release of a variety of substances, including some pain-causing substances. The pain-causing substances enter the whole body with blood circulation and cause generalized pain. At the same time, the body’s defense function is weakened after a cold, the body’s internal environment is affected, the metabolism is slowed down, and the lactic acid produced can not be discharged from the body quickly, and a large amount of lactic acid accumulates in the muscle tissue, which causes generalized aches and pains. In addition, viral and bacterial infections can also lead to an increase in the release of prostaglandins, increasing the body’s sensitivity to pain and further aggravating generalized soreness. If there is a combination of bacterial infection, the body’s white blood cells increase, hemoglobin decreases, oxygen carrying capacity decreases, the brain lack of oxygen, headache, dizziness and other symptoms. Generalized aches and pains after colds are mainly caused by the invasion of pathogenic bacteria, so antiviral or antibiotic treatments for generalized aches and pains after colds can mostly be relieved.
