Nose Bleed : Symptoms & Causes
A nosebleed is loss of blood from the tissue lining the nose. Bleeding most commonly occurs in one nostril only.
The nose is a part of the body that is very rich in blood vessels (vascular) and is situated in a vulnerable position on the face. Any trauma to the face can cause bleeding from the nose. This is common in dry climates, or during the winter months when the air is dry and warm from household heaters.
(1) Bleeding from one or both nostrils.
(2) Frequent swallowing.
(3) Sensation of fluid flow in the back of the nose and throat.
