I keep having congested chest, coughing up mucus and constantly blowing my nose. My chest has felt really tight all the time and I have shortness of breath. I live in a college house with 5 other people and I took antibiotics like 9 months ago or so for the same problem but I only took 3 days worth of it and i do not know if that messed with my immune system. I don t particularly eat healthy or exercise anymore. Just wandering what you think and also worth noting I took antibiotics once again this semester and I still felt congested. I was wandering if I get on one of these healthy diets and sanitize our house somehow if there is any possible way I can get rid of this mess or if I need to go to the hospital or what? I may be a little paranoid just want to be on the safe side
