Hi, had sore throat/fever/congestion bug but seem to be getting over it. Sinuses very blocked but blowing nose yields nothing. Sneezed and felt movement inside my face. Almost like a pop? So I blew my nose hard to see if I could shift mucus and this came out! What is it? It doesn’t feel like ‘snot’ it’s very bodily tissue in its texture. Still blocked although could feel release when it came out.
