Why is there hair growing on the wound on the child's leg?

There are the most mosquitoes in summer. Once bitten by mosquitoes, the skin will become red, swollen or itchy. Adults have a strong control ability and will not scratch them with their fingers, but children are different. If the bite site is scratched, it will affect the healing speed of the wound and increase the chance of infection. Some children even have hair growing on the wounds on their legs.

Don't get close to water.

Third, during the healing process of the wound after trauma, a layer of white substance appeared. It may be that the wound was not disinfected and cleaned properly, the wound surface was contaminated, or medical powder was sprinkled on the wound. It may also be caused by wound infection. If there is no obvious pain, you can wipe off the white stuff with a cotton swab during disinfection to see if it can be wiped clean and whether it will regenerate. If not, then it is not a big problem. Just make sure the wound is dry and clean.
