I am spitting up streaks of blood in my saliva. i did throw up pretty violently right before but there was no blood in it that i could tell. ed time?

Very possible: its just from irritation and some disruption of small capillaries monitor it if it persists see your doc

Yes: Hemetamesis and hemoptysis is vomiting and coughing up blood. Throwing up can sometimes rupture blood vessels in your esophagus or if you have a cough blood vessels can rupture. Nonetheless it is recommended you go to the emergency room for a more complete history and physical for this symptom. Good luck.
