You can eat eggs when you have a fever. Fever consumes a lot of protein in the body, and eggs themselves contain a high level of protein and other nutrients, which can replenish the protein consumed by fever, but do not have the effect of reducing fever. If the fever is caused by a cold, you can take anti-cold medications such as cold granules and aminophenol pseudoamnesticide tablets orally, which can treat and relieve various symptoms caused by a cold, such as fever, headache, nasal congestion, sore throat, etc. If the body temperature is greater than 38.5℃, you can take ibuprofen, acetaminophen orally, or use indomethacin suppositories in the anus, which has the effect of antipyretic and analgesic, and can play a fast role in reducing fever. Eat a light diet and less spicy, stimulating and oily food to avoid fire and phlegm, which can cause coughing.
