Colds that cause severe coughing and frequent coughing can cause the chest muscles to spasm and cause pain in the lungs. Cough, phlegm and cold medicines should be used in time. Commonly used cough and phlegm medicines include Carbocisteine Oral Liquid, Ambroxol Oral Liquid, as well as cold and flu granules, cold and flu capsules, or ordinary tablets. If the pain in the chest or lungs caused by cold and cough is more serious, Yunnan Baiyao Spray can be used externally to invigorate blood circulation and remove blood stasis and relieve pain, and anti-inflammatory laryngeal tablets and local nebulization can be taken if there is pain in the throat.
