I was sick a few weeks ago. I can't tell if it was allergies or cold. I went to the doctor and he gave me allergy shots and a prescription.

My runny nose, sneezing, coughing, watery eyes definetly stopped. As I gradually got better, I started having these periodic headaches that would last all day for several days. From what I read, it is a symptom of me having a cold. So I took medications to remedy the cold.

Now I feel perfectly fine but I still have this mucus buildup in my throat for the last several days. There is an occasional runny nose and cough but very few. I took Mucinex to loosen up the mucus so that I can cough it up. It was green initially but now I don't know why I still have drainage issues and mucus buildup.

Any help is appreciated.
