In the last week, I've blown my my nose and on two occasions, a small, 1-1.5 cm string-like substance came out and almost looks like a small, brown worm. No discomfort, no blood, no movement or activity. I am otherwise very healthy, good diet, have never had any nasal or sinus problems and do not get sick with any ailments in the past 30+ years. I am 52 years old, male. Thank you.
