What causes a nose bleed and why can you sometimes feel ill after one?

Answer 1

Most of the time this is caused from the blood vessels in the sinus cavities being at the surface and weak.Alot of times its due to sensitivity or allergies.Try taking more vitamins like vitamin b-12 or a good supplemental vitamin.Also you will want to add moisture to the air when you sleep, like re adjust your humidifier in your home to up the percentage of moisture in the air.A vaporizer works well too.Dry air usually ups the sensitivity to air born irritants like dander and dust that can cause sensitivity.
You feel weak cause of the blood loss and the fact that some drains down your throat to your stomach which can irritate your stomach and make you nausea's.
