I Am On Week 5 Of Being Ill. I Have

I am on week 5 of being ill. I have chest tightness and hard time breathing, had a fever in the first 3 weeks. I was coughing up fluid the first 3 1/2 weeks. I got antibiotics for 10 days and took a anti-inflammatory as well as a cough syrup. I started to feel good, the last 4 days my symptoms have come back again. Other symptoms are fatigue, my throat feels like it's closing off and restricted. My throat is sore and dry. I now have a cough that is spasmatic, but dry.
