I Am Recovering From The Flu, I Have Had It

I am recovering from the flu, I have had it four about four days now, and my symptoms have been rapidly diminishing. The one problem is that I have had a lot of lung congestion and have been wheezing some. Sometimes a part of my lungs seem to get clogged off and i have to inhale deeply for it to open, and there is a strange delay and a weird noise. What can I do to speed up my recovery and is anything wrong with me?
