I have never had one before. Now I'm a very stressed 20 yr old. And I got one Wed. And today I started throwing up randomly even though I feel fine and my nose started bleeding again. Should I see a Doctor?

Anytime you have frequent nose bleeds and also having other symptoms like vomiting defiantly you need to see a doctor. To rule out anything series. There could be a number of things going on, Even neurological, pregnancy? So please visit your doctor asap, if you can not see your family doctor I would suggest you go to the emergency department.

I agree, see a doctor. If you swallow any of the blood that, in itself, can cause vomiting. Nose Bleeds And Vomiting (http://www.righthealth.com/topic/Nose_Bleeds_And_Vomiting?p=l&as=goog&ac=519&kgl=7750822)
