What should I do if my nose turns red from a cold? First, you should avoid rubbing your nose. You can relieve the swelling of the nasal mucosa through oral medications. The redness of the nose is due to the expansion of local capillaries. Additionally, external stimuli, pinching the nose, runny nose, and sneezing are all directly related. You can choose to take vitamin-based medications and medications known to affect glandular secretion for symptomatic treatment. If there is acute inflammation of the nasal mucosa, you should also choose some antibacterial drugs for treatment. Drink more water and rest more; generally, you will gradually recover in about three days.
