I have had a fever for the past 5 days. I think it finally broke today but it's hard to tell without a thermometer. My lungs hurt every time I take a normal breath and I cough every time I take a normal breath. Any physical activity puts me into a crazy cough fit. I can't lay on my back even for a second,if I lay on my back I can't breath and start coughing even with short breaths. Every now and then I cough up green mucus. I am not a smoker. Any ideas what's wrong with me?
