Recovering from a cold but wheezing and some pain in right lung?

I recently caught a cold that has been going along NY for a while and I was very congested with a bad sore throat . I didn't get a high fever but sometimes when I woke up I would cough up yellowish phlegm and some when I blew my nose. Now the runny nose and sore throat is gone and there is no fever but I am left with wheezing and some pain in my right back. I am 17
