If you have a cough and itchy throat, it is recommended to use phlegm medicine first. If you don’t like to use medicine, you can also use some hot steam to do nebulization, inhale some hot steam, for example, with a cup of hot water, and then try to use your hand to hold it, and then try to suck the steam into the airway as much as possible, and then see how the phlegm is discharged. If there is phlegm in the airway that causes itchy throat and cough, the phlegm can often come up by taking deep breaths when inhaling the hot steam, and if the phlegm comes up and does not cough, it means that the itchy throat is related to the discharge of phlegm. In addition, if a respiratory infection is not completely healed, the remaining residual phlegm often sticks to the airway or throat when it is slowly discharged, and at this time it will stimulate the airway or throat and cause coughing. If no phlegm comes out from the phlegm-removal medicine or steam nebulization, this may be a cough of Yin deficiency. Yin deficiency cough often occurs after an external infection or respiratory tract infection, such as bronchitis or pneumonia, due to insufficient replenishment of water during the inflammation period or a prolonged fever that overtaxes the body. This time need to nourish Yin and clear the lungs, you can eat some cool and moist things, such as boiling some silver ear soup, boil some pear water, this time is available. Another thing is to identify allergic cough, because sometimes allergic pharyngitis can also cause itchy throat and cough. This is easier to identify if you have allergies, such as previous allergies to any medications, allergies to anything or allergic rhinitis or dermatitis, or if there are other people in your family with a history of allergies. If this is the case, you can consider whether it is an allergic cough. Of course, if it is difficult to identify these yourself, try to go to the hospital and ask your doctor to help you identify these cases.
