Colds often cause fever, nasal congestion, runny nose, and generalized muscle aches and pains. Therefore, it is more common for colds to cause generalized body aches and pains. Colds are mostly caused by viral or bacterial infections, which in turn cause fever. High body temperature, more than the body’s ability to withstand, will cause abnormal energy metabolism, the whole body muscle anaerobic fermentation aggravated, lactic acid production increased, lactic acid excretion slow. Lactic acid production increases and accumulates in the muscle tissue, causing generalized soreness. Appropriate antipyretic treatment can relieve the symptoms.
