How to solve frequent coughing and what is the reason

Patient's question:

Did it? Coughing has been going on for a long time? No high fever. Past treatment and effectiveness: Taken cough medicine? Many different kinds? Still not effective. What kind of help is needed: How to clear the lungs? Don't know what caused it

Doctor's answer:

The reasons for your condition are mostly bronchitis, pneumonia, pleurisy, tuberculosis, or cor pulmonale. It is best to go to the hospital for a detailed diagnosis. Suggestions: If you want to self-treat, you can take Cephalexin and Amoxicillin capsules to see how effective they are. Additionally, the Chinese medicine Fritillaria cirrhosa stewed with pear can help with phlegm and cough relief. If it is very severe or particularly painful, it is recommended to go to the hospital, as it will be more effective.
