If there is no acne or bacterial infection around the nose, it will not cause meningitis. Meningitis is caused because there is no venous valve in the facial vein, and the blood can't go back. Some people think that there are abundant veins around the nose and corners of the mouth, so once infection occurs, bacteria will enter the brain with blood, causing infection in the cavernous sinus of the brain, leading to intracranial hypertension and even meningitis. Therefore, the acne around the nose and corners of the mouth should not be squeezed, commonly known as the danger triangle. I wonder if pinching my nose can make it stand up. Anyway, pinching your nose will not cause meningitis without infection.
