I just got over a virus or the flue or something. I was running a fever between102 - 103.6 for the past 2 days. Now I'm like congested and can't breathe. When I blew my noised I notice a tissue like substance come out of my nose. Yes that kind of freeked me out. It was a big glob. Is it o.k. to lose nasal tissue like that or is this something I need to be concerned about.
