From the photos, it seems that little by little, the pores are filled with street plugs, and the sebaceous glands of the skin are inflamed (similar to acne). There are many sebaceous glands in this part, which have been clamped all the time, and the blood vessels can't, so it is easy to be inflamed. In addition, there are bacteria in your clip, which can easily cause inflammation. Also, I don't know what material your clip is made of, or whether you have paint and other coatings, which may also cause allergies to the skin. Don't squeeze yourself, apply hot water, go to the hospital, be disinfected and cleaned by the doctor, and you will be fine after taking the medicine. Don't be too nervous, but hurry, it's still superficial now, and the scar won't be serious after treatment. It's just that I won't pinch my nose again in the future. My nose is not very good, but there are many future troubles.
