Do I need to see a doctor about this?

I don't want this to be too long, so I'll try to shorten it.

- I got sick on Wednesday: Freezing, headache, and sore throat. Thursday was the same, except I couldn't talk at all.
- Friday (or today): Woke up with a stuffy nose, I could talk a little, headache wasn't as bad, and coldness went away.
- Sometimes I feel faint when I stand or move. It feels like blood is rushing to my head.
- My ears keep ringing at random times throughout the day. They hurt as I type this.

It seemed things were going well, but I noticed this weird taste in my mouth. It began around noon I think, and hasn't gone away. It wasn't until I blew my nose (and saw red) that I realized I was tasting blood all day. I checked my gums and they're not bleeding.

What's wrong with me? To shorten it: I taste blood coming from my throat, I had a nose bleed, my ears ring and hurt, and I get lightheaded often. Is this a bad sign? Do I need to see a doctor?
Yes!!
No, you're fine.

If people could stop being sarcastic, that'd be great.
