I was allergic to wearing a belt before, and the skin at the belt joint was itchy, red and black.

First of all, prevention+treatment.

1) prevention

Don't fasten your belt too tightly. Pants are mainly supported by waistlines. Pay attention to the metal part of the belt and don't use cheap belt buckles. They are all made of iron or aluminum. Sweating is easy to rust and produce oxidation to infect the skin. Use heavy metal belt buckles. Such as alloys and steel materials.

2) treatment

Mixed treatment of oral and external drugs. Replace the belt first. Prevent reinfection. Apply skin medicine every day. Oral Chinese medicine pill for treating skin allergy.

I just went to the traditional Chinese medicine hospital, and it will be cured soon after oral administration and external application. Piyanping is not needed for external use, and dyclonine can replace it. Pay attention to oral administration, don't eat indiscriminately, and be sure to use the medicine configured by the hospital.
