Hi I started with a slight sore throat about 6 days ago it has become phlegm deep in the throat and a pretty dry sore throat i am coughing but mostly due to the phlegm a very lite fever at times mostly i over heat when i get dressed up and start moving around have headaches for 2nd day now but i think they are from coughing and sore neck muscles lungs feel fine no nasal issues, just sore throat, phlegm, and cough. dont have insurance and dont want to goto doctor if i dont have to, does it sound like a common cold or strep or something else.
