Yes. I have had an ongoing pill sniffing habit for 3 years now mainly only percocet. I had done cocaine for a couple years before this. Mornings I have alot of fluid, thick, grizzle type and lots of bright red blood in the snot I blow out in the morning. Back of my throat burns insanely when I go an hour or 2 without sniffing a percocet. And my throat has been swelling and hard to swallow, almost like a toncilitis swelling feel. Ears are tingy feel when I am having trouble with swollen throat feeling sometimes impossible to swallow.
