According to your symptoms, it is mostly caused by upper respiratory tract infection. In addition, it depends on whether there is chronic pharyngitis.

I suggest you go to the hospital to take an X-ray of your lungs. It is necessary to use anti-inflammatory drops. At the same time, you can take some oral drugs, such as Kebiqing and Nianci syrup, and pay attention to drinking more water.
