Why does my nose bleed after I blow it? It starts to ich & then it starts to bleed.

Epistaxis . Is nose bleed. It can happen with nasal allergies(running nose, sneezing, or itchiness), dryness in nose , getting hit on nose (sneezing is a way of getting hit in nose- lots of force when sneezing). This cause capillaries to bleed. Take zyrtec, apply vaseline inside nose. Hope it helps.
