Irritated throat days after running?

2 days ago I ran ashly for the first time in months and it was pretty wet and cold out, and ofcourse I felt dead after...later that day my throat felt irritated like theres flem or something, but when I clear my throat it doesn't really help. Its only there when I breath out or put pressure on my throat...also my voice is deeper because of it, and my nose is a bit congested, and its been like this for a couple days. So do you think its just short term irritation from running so hard and stirring up flem and stuff, or do you think I'm really sick?
