If there is booger in the nose, you can pick it, but if you pick the booger, it may cause damage to the nasal mucous membrane and even nasal bleeding. Because the nasal mucosa is very rich in blood vessels, if there is external force caused by the nasal mucosa damage or the nasal mucosa is relatively dry, picking the nose is easy to cause nasal bleeding. If there are more boogers, you can consider using some lubricating drugs to lubricate the nasal mucosa, such as compound menthol nasal drops to drip the nose, 1 time 1-2 drops, 3 times a day to lubricate the mucosa of the nasal cavity, but also can be added to the physiological sea saline to do the nasal cavity rinsing. If the mucous membrane in the nasal cavity is not dry, there will be less boogers, which will prevent bleeding in the nasal cavity, and you can stop picking your nose. In addition, if there is a lot of bleeding when picking boogers, which is not easy to stop, you should go to the hospital to further check the situation inside the nasal cavity.
