Fever, headache and generalized aches and pains are often systemic symptoms caused by viral or bacterial infections. When viral or bacterial infections occur, these bacteria or viruses will grow and multiply in the body and produce a large amount of toxins, stimulating the body’s thermoregulatory center and shifting the body’s temperature regulating point upward, resulting in fever. When the body temperature rises, the body’s metabolic rate rises, causing a large amount of anaerobic glycolysis, which produces a large amount of lactic acid that accumulates in the muscular system, resulting in body aches and pains. When you have a fever, the blood vessels are easily dilated, leading to congestion in the head and headaches. The effect of anti-inflammatory treatment for cold virus or bacteria is often better, for example, you can take Pudilan anti-inflammatory oral solution for viral infection and cefixime for bacterial infection. For fever symptoms, it is recommended to use ibuprofen suspension for fever reduction.
