Hi Everyone, I am a overall healthy woman, but I,ve noticed that everyonce in a while, during my showers only, that I sometimes cough up this black chalky stuff, { no blood }, also my nose has been running off & on for a while as well. I dont have a persistant cough or anything, its just when I shower, its weird & scary, & yes I do smoke, & trying to quit. Anyway, Im kinda scared, I mean what smoker doesnt worry about the big C, so if anyone can explain to me what this charcol weird black stuff is, Id appriciate it. Thanks Penelope
