Because there is a layer of mucous membrane in people's nostrils, it is he who makes our noses run at ordinary times. When people catch a cold, bacteria and viruses can make trouble in the nose, leading to inflammation of the nasal mucosa, congestion and swelling, and a lot of runny nose. In addition, there is a passage between the nose and eyes, and some tears enter the nose along this passage, so there are more runny noses. When you have a cold, your nose is usually blocked, so you often twist your nose. At this time, your nose will have a feeling of soreness, which is the same as the lacrimal gland. You also stimulate the secretion of lacrimal gland to flow into the nasal cavity through nasolacrimal duct, so you often have a runny nose, but it is not very sticky. This is the cure for frequent runny nose: it is well known that a cold can cause runny nose. But why do some people often have runny noses after catching a cold? A runny nose during a cold is called acute rhinitis. At this time, the nasal mucosa is congested and swollen, and the secretion of glands increases, forming nasal mucus. At first, it was clear water-like, and it gradually became purulent after 3 ~ 5 days, and it could be cured after 1 ~ 2 weeks. If acute rhinitis recurs, and the nasal mucosa is congested, swollen or even thickened for a long time, it is chronic rhinitis and will often have a runny nose. When there is a runny nose, let the child blow it out by himself. To have a correct way to blow your nose, hold down one nostril and gently blow your nose. At the same time, the nasal cavity should be unobstructed, otherwise the nasal mucus in the paranasal sinuses is not easy to blow out, and purulent nasal mucus can enter the paranasal sinuses or eustachian tube to cause otitis media. Nasal drip of ephedrine and other vasoconstrictors can reduce nasal discharge, but patients with atrophic rhinitis should not use such drugs. When dropping the medicine, you should prevent the medicine from flowing into your mouth, because the child feels bitter and will not let the medicine drop again in the future. At the same time, in order to make the liquid medicine drip evenly into the nasal cavity without flowing out quickly, it is necessary to have a correct dripping posture. Paranasal sinusitis with excessive nasal discharge can be treated by transposition therapy or puncture and lavage in the hospital.
