I have a severe sore throat, nothing seems to soothe it. I also have a dry cough that doesn't seem to stop, my chest hurts from coughing so much. I think my chest is congested but I can't tell if it is or not because I have a dry cough and my chest hurts. It's so bad I'm thinking about going to the hospital

How can I fix this!!!

I've been trying DayQuil and NyQuil and they don't seem to do ANYTHING. They don't stop the cough and only ease my sore throat slightly. Even when I take NyQuil I can't sleep through the night because my sore throat wakes me up. Would DayQuil Sever Cold and Flu be better?

What else can I do?
