well i tell you whatever you do dont hold your hand over your mouth to conceal it, i used to do that and blew a blood vessel in my nose out from the pressure and i bled like a broadhead hit me, i had to go get it burnt shut at the hospital, talk about a bad day!! now i just cough and use my grunt to try to conceal it! ill cough then grunt a few times!! i also try these nose drops, over the counter called ponaris oil, takes the sinus itch away and cleans out the hole area quick!!
