Severe coughing after a cold can cause pain in the chest. Patients with symptoms of cold can improve the blood routine, C-reactive protein, calcitoninogen, mycoplasma antibodies, chest X-ray and other related tests, and assess the causative organism according to the test results, and take different targeted treatment for different causative organisms. Viral infections can be treated with antipyretic drugs, bacterial infections need to be treated with antibiotics, while mycoplasma infections need to be treated with macrolide antibiotics, or quinolone antibiotics, which can be very effective in avoiding severe coughing and can also significantly reduce chest pain caused by coughing. If the cough is severe, oral cough suppressants such as Glycyrrhiza glabra tablets, Pulmonary Cough Compound, Su Huang Cough Capsules, Powerful Loquat, etc. can be used.
