I've always gotten bloody noses, expecially in the winter, so its no supprise to me, but the last two days, I've gotten really bad ones. The first time, I was driving down the highway, and it started, so I grabbed a tissue...no big deal. It instantly filled my nose though, and went down into my throat. I ended up pulling over real quick to spit out blood, and it kept just pouring out for a few minutes before I could get it to stop, enough came out to make me feel light headed for a while. Thankfully my g/f was with me, so I was able to have her drive home. Last night, it happened again for the second day in a row, I was sitting at home, watching TV and it started, and just poured out for almost 10 minutes! I've talked with a couple people who said I probably just have a sinus infection and that it'll stop on its own. I am curious if I should see a doctor about it anyways, I've never had a bloody nose that bad, or that made me feel light headed at all.

Yes, I would suggest you see a doctor if that severe, especially if it made you light headed.
