I used to cough, but after a period of treatment, I found it was pharyngitis, so I spent a long time treating it. I suggest you have a look. Pharyngitis can also have an irritating cough.
I still have a bad cough and a choking throat, which may also be caused by pharyngitis.
I also had an X-ray, and the electrocardiogram was fine. Cough may be caused by other diseases. I asked an old Chinese doctor, who felt my pulse and said that I had a nervous cough. If you focus on food and air, you may also have a good effect.
At the beginning of my treatment, I also doubted this branch and that branch. Recently, I also suspected that I was a precursor to tuberculosis. I have been coughing 1 year, and it is intermittent every day. If the fluoroscopy is fine, it's not a lung problem.
Alas, coughing is really annoying. ...
I hope you pay attention, exercise more, don't smoke, drink and eat irritating food, and don't catch a cold. ..
