At the same time, pharyngitis is accompanied by retching, hoarseness and throat discomfort. I always feel something commonly known as foreign body sensation, such as clearing my throat. Of course, for dry cough, you can also get some small dietotherapy, such as rock sugar Sydney, which is also quite good. Professional treatment is generally based on Chinese medicine, which comprehensively regulates lung yin deficiency, repairs damaged immune system and improves immunity. You should cooperate with the doctor to take medicine.
