I have come down with something and I'm not sure exactly what it is. At first it was a sore throat and cough which I took Delsum day time cough & cold for.. And it lastested about a week. Two days ago I started having difficulty breathing. I had shortness of breathe and couldn't get a full breathe for almost 2 hours straight. I was afraid I might have to have gone to the emergency room. I felt very week and everything knocked the breathe out of me. Last night my nose blocked up and I couldn't sleep because I couldn't breathe easily. My nose, ear, etc are all aching and sore. I'm trying to find the best medications and things to treat my symptoms but I want to know if I'm dealing with the common cold or a flu.
