Acute bronchitis, cough with phlegm and sore throat, what to do?

Question
Hello doctor,
About half a year ago, I had an X-ray and was diagnosed with acute bronchitis by the doctor. I have taken medicine, but I still feel that my throat is always phlegmatic and I have a cough and sore throat from time to time. Sometimes, he has a sharp pain in his left chest (this phenomenon is common). A few days ago, I went back to another hospital but they said my lungs were normal. Compared to the film half a year ago, the faint mark in my left lung is still there. The doctor told me to ask for acute bronchitis, cough with phlegm and sore throat, what to do? Please advise, thank you doctor.

Hello,
With the question “Acute bronchitis, cough with phlegm and sore throat, what to do? ", the doctor would like to answer as follows:
For common acute bronchitis caused by viruses, you should keep warm after treatment. If respiratory symptoms persist and increase, you should see a pulmonologist, who can test your respiratory function to rule out chronic inflammatory diseases of the airways: Asthma.
For the opacity of your left lung that remains after 1 year of follow-up, you should also provide the 2 x-ray films to the pulmonologist. Many cases of lung opacities with old inflammatory lesions only need to be monitored, however, if respiratory symptoms: Cough, chest pain, especially coughing up blood appear and recur, you may need More in-depth exploration: Bronchoscopy, diagnostic biopsy,...
Ideally, you should visit a respiratory specialist for specific advice.
