If you simply have a runny nose and nasal congestion, you need to judge what kind of cold you have based on the color of your nasal discharge or the accompanying symptoms of your whole body. Firstly, if the runny nose is clear and accompanied by cold, headache, weakness and general muscle aches, it may be a cold, so you can take some cold and fever pellets to treat it. Second, if the patient has a yellow runny nose, accompanied by a sore throat, fever, coughing yellow sputum and other symptoms, it may be a viral cold, you need to use antipyretic and antiviral drugs to treat, such as Pu Di Lan, but the specific situation requires patients to go to the hospital for consultation. However, in addition to cold, runny nose and congestion may also be allergic rhinitis, which needs to be treated with anti-allergy drugs such as loratadine, cetirizine, and nasal inhalation hormones.
