I have been coughing up blood for a couple weeks now. My throat flares up and Its hard to breathe but then goes away and comes back every other hour or so. I am not sick to my knowledge and have no other symptoms. What could be causing the blood?
Coughing up blood can be a serious symptom. If the amount of blood is small with slightly tinged mucous, it is probably just bronchitis and your severe cough is breaking capillaries. A round of antibiotics will clear that right up, so see your doctor soon. If you are coughing up larger amounts of blood, go to an ER, hospital.
I frequently have massive infections with no other symptoms except a nagging cough (sometimes slightly blood tinged) or just a nagging sore throat.
