The most common form of long sore on the nose is folliculitis or furuncle, which causes local pain, redness, swelling, tenderness, etc. Nose sores are mainly due to the rich sebaceous glands and sweat glands in the nose, so this place is particularly vulnerable to infection by bacteria, especially pyogenic bacteria, which can form furuncles. Once there are furuncles, this place cannot be squeezed because of its anatomy. There is no valve in the vein at this place. Normally, the vein runs in one direction and cannot flow in the opposite direction. But there is no valve at this place, so the blood can flow in the positive direction. It can also be reversed. If squeezed, it will lead to backward flow, which can enter the brain and cause intracranial infection, so it is called the danger triangle area. There are furuncles in this place. Do not squeeze it. Take antibiotics orally and use Baiduobang ointment locally. Do not eat fried spicy food and drink alcohol.
