ive been sick for 1.5 weeks with a common cold; soar throat, runny nose, temp 99-100, loss of taste and smell. right now its only my nose and kinda my ears. no temp. but i keep spitting out mucus and when i blow my nose (only when i feel it is really necessary, i never blow too hard) this huge mucus/blood glob comes out (about the size of two full thumbs). The mucus is orange and blood is dark; all looks like one... and keeps getting darker. about 4-5 times a day i would blow this out of my nose and its only from my left nostril. will it go away in time, or is this something that i should get checked?
