The lack of strength and energy of the whole person after a cold is due to the invasion of the upper respiratory tract by pathogens such as viruses and bacteria, which leads to the production of a large amount of toxins that enter the bloodstream and cause general weakness. Further colds can cause a large amount of protein depletion in bones and muscles, and the accumulation of lactic acid can also cause muscle aches and pains, weakness and lack of energy in the body. Clinically, colds can cause fever and other calories such as proteins and sugars to be consumed in large quantities, and the energy to feed other cells in the body is significantly reduced, resulting in weakness. Symptomatic treatment can be carried out through relevant medications, including Lianhua Qingfei capsule, Pu Di Lan oral liquid, Xiyamping injection and Phlegm Fever Qing injection, etc., which can help to improve the condition.
