Help please

you may have bronchitus; do you smoke cigs? is emphysema a running factor in your family gene pool? are you taking any meds?

a "smoker's hack" is not uncommon in everyday (pot) smokers. not sure why, but it's a fact. the blood is probably coming from your nose; are you prone to nose bleed?

please answer these, i'll see if i can come up with an answer for you

Nope i dont have bronchitus, i went to the doctor a month ago and he said that i had a minor respiratory infection and gave me some anti biotics... and no i dont smoke cigarrettes, emphysema is not common throughout my family and i got done taking anti biotics about 2 weeks ago
