Nose bleeding happens when blood comes from the nostril. There are a few possible causes for the bleeding from the nose, such as dry air, picking the nose, allergies, infections, or blowing the nose. A typical way of classifying a nose bleed is anterior nose bleed (which is mean nose bleed in the front part of the nose); on the other side, posterior nose bleed means nose bleed in the back part of the nose. Blood drip from the nose is usually the first symptom that notices a nose bleed, and the light-headedness also indicates problems. In order to take care of a nose bleed, first use the press in the nose, then use saline nasal spray, and lastly, go to the hospital.
