Dear Diana, hello
Nose has a region which is highly vascular known as Kiesselbach's Plexus in the Little's Area, an area near the anterioinferior part of nasal septum
to this area result in bleeding.
Nose bleed is also common in cold infection. Bleeding can be stopped by placing ice or cold compress near the tip of the nose. Nose picking by finger should be avoided as this furthur injures the area.
Nasal mucosa shoul be kept moist by using saline nasal spray
after consulting your ENT specialist
I hope this is useful to you.
