Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the sore throat with expectorations especially in the morning.
With sore throats, most of the time the soreness is worse in the morning and improves as the day progresses.
Commonly, sore throats are caused by viral infections. This means most sore throats will not respond to antibiotics. When the nose or sinuses become infected, drainage can run down the back of the throat and irritate it or the throat itself can be infected. Some viruses can cause specific types of sore throat. For example, Coxsackievirus sometimes causes blisters in the throat, especially in the late summer and early fall. Mononucleosis and the flu can also cause specific viral throat infections. Sometimes breathing through the mouth will cause a sore throat in the absence of any infection. During the months of dry winter air, some people will wake up with a sore throat most mornings. This usually disappears after having something to drink. In addition, allergies can cause a sore throat. Whether or not you are likely to develop allergies is often passed down through families. If both your parents have allergies, you are likely to have allergies. And in your case you have a family history of allergy. With a sore throat, sometimes the tonsils or surrounding parts of the throat are inflamed. You might undergo blood tests and throat culture to find out the cause of sore throat.
You must consult ENT doctor for proper diagnosis as the same cannot be made online.
Hope this helps. Take care.
