I Have Had A Sore Throat For About A Couple

I have had a sore throat for about a couple days, no cough. I took a flash light and saw blood. I couldn't taste it, it wasn't running or anything. I drank some water and it went away. When I checked back awhile later there was a red vein? *also thought I should add I had a really bloody nose yesterday that lasted about an hour, but it eventually stopped. I didn't swallow much blood, and I think It would've been one from my throat by now?*
