During a cold there can be symptoms of non-ventilation of the nose and even a sore throat, which can be treated accordingly. If the nose is not ventilated, accompanied by a large amount of runny nose, you can take some medication to inhibit nasal secretion, such as chlorpheniramine maleate. This is a histamine inhibiting drug, which can block the histamine receptors and inhibit the secretion of the nose. In addition, you can also choose drugs such as pseudoephedrine hydrochloride that constrict the blood vessels in the nose, and there are many cold and flu medicines that contain both of these ingredients. Sore throat is mainly due to inflammation of the pharynx, which may be just redness of the pharynx, or there may be swollen tonsils. In this case, you can take some tablets, such as Golden Voice Throat or Western medicine Huasu tablets, which can help to relieve the sore throat. If the sore throat is caused by bacterial infection, it is likely that there are pus spots on the surface of the pharynx, which should be treated with antibiotics.
