I've had a cough and minor fever that started about 10 days ago. I took some medicine for it, but my cough still hasn't gotten any better. The fever usually kicks in during the evening, but not so much in the noon. Lately, my cough has gotten really bad, and it's so intense sometimes that it makes me vomit. I've also noticed a bit of blood in the mornings after coughing. The cough feels like it's coming from my chest rather than my throat. Could you help me figure out what might be going on?
