It is also relatively normal to have a nose bleed when you have a cold. A cold is originally an infection of the upper respiratory tract, including the nose, throat and pharynx, caused by a cold virus or bacteria. When an infection occurs in the nasal cavity, there will be congestion and edema along with inflammation, and nose bleeding can easily occur. If there is no obvious abnormality, nose bleeding is caused by inflammation of the nasal mucosa, and nose bleeding can often be relieved by using cold medicine to relieve nasal congestion and edema. It is recommended to use aminogalactone capsules and vitamin C silver forsythia tablets to adults for treatment. In the case of children, they can be treated with pediatric blackberry clearing granules, pediatric cold and flu clearing granules or pediatric aminophenol pseudomal dispersible tablets. If bleeding caused by dryness of the nasal mucosa occurs, topical petroleum jelly ointment can be applied to relieve the symptoms of nose bleeding.
