told me to do the following:
- If you've had a bloody nose in the past day, and you've got another one, blow your nose first. It will get the old clots out and provide a fresh surface for the new clot to form
- Pinch your nose -- not too hard, but enough to seal the nostril shut and give the blood time to coagulate.
- Don't tilt your head back or lie down. It will cause the blood to get into your sinuses or into your stomach (blecch), which can make you sick.
- Don't pick at it or it won't get better. (and it's rude, too.)
