Why does my nose bleed it bleeds for no reason

I . I don’t know what is making your nose bleed. Some common reasons can include: nasal congestion or nasal dryness, high blood pressure and excessive use of decongestants. Being at a high altitude, trauma to the nose, picking the nose, or blowing the nose hard. Bacterial and viral infections can increase the risk as well as bleeding disorders. There can be recurrent nose bleeds if a small vessel in the nose is broken.
