I’ve been coughing up blood today?
I’ve been coughing up blood today, and brown mucus prior to this. The blood is mixed with mucus, bright red and bubbly. It has eased for now, and the quantity of blood wasn’t a lot either. Also, I’m a smoker, there’s no one with TB or fever or anything around me. The brown mucus is there for around a week and the blood just started today. What should I do? And honestly, should I be worried? Pls let me knew whether I should worry or not.
