I have a sore throat and there is blood in my phlegm?

I was just searching for the exact same symptoms, i have this too, exactly the same word for word!! I was worried about the blood too, but i checked around and it looks like it's just the cold. I am personally going to wait another day and see how i feel, and if it goes away on it's own, but it looks like alot of people have this same cold right now. Good luck, i hope you feel better too!
