Sore throat, dry itching and cough often result in infection of the upper respiratory system, especially pharyngitis. Once pharyngitis occurs, it is often due to viral infection and bacterial infection. In addition, mycoplasma and chlamydia infection may also cause pharyngitis. When the throat is inflamed, there will be congestion and edema in the throat, accompanied by redness, swelling, heat and pain. Therefore, you will feel sore throat and dry itching. Cough is mainly due to the stimulation of inflammation. In addition, the throat will also secrete inflammatory exudates, which will also lead to cough. It is better to use anti-inflammatory drugs. For upper respiratory tract infection, the commonly used anti-inflammatory drugs are Chinese type, such as Pudilan anti-inflammatory oral liquid and Lanqin oral liquid. In case of bacterial infection, such as suppuration and leukopenia in blood routine, antibiotics such as cefadroxil should be used for treatment.
