Hi I am concerned, I keep coughing and blowing out mucus balls. I also have had nasal drip, bloody nose and chest pains, this has been an ongoing thing for well over a year, but when I spoke with PCP about it, he said the mucus balls shows possible infection, but to not show concern. It has never stopped and now I am experiencing other things and getting worried, chest pains, exhaustion and bloody nose blows at times?
