I have phlegm in my throat when I speak.

This is a symptom of chronic pharyngitis. The main manifestation is that the nasopharynx is dry and uncomfortable, and it is not easy to cough up viscous secretions, that is, "there is a foreign body sensation in the throat, which can't be coughed up and can't be swallowed", so patients cough frequently and often feel sick. Severe cases have symptoms such as hoarseness, sore throat and headache.
