Could there be a cure for sneezing blood?

Bloody mucus: Many times when we sneeze and the nose gets very dry, the mucus membranes along the septum can get irritated and the capillaries rupture leading to bleeding. If this continues, you might need to increase the humidity in the bedroom when sleeping, put a little white petroleum jelly in the nasal passages at night. You might also need to see an ENT if this continues.
