The skin had a rash before. Later, when the weather cooled down, the skin cracked and formed a wound. It lasted for a week, because the wound at the movable joint had not healed. At ordinary times, I just wiped iodophor, but it didn't get better
Hello, according to the description and photos, there are wounds on the back of the hand, which should be caused by local epidermal keratinization infection and other factors. It is recommended to disinfect with Iodophor cotton swab every day in the near future, and then apply baiduobang. It is best to wrap it with sterile gauze after disinfection. Generally, the keratinized part of scab will gradually fall off in 2 ~ 3 weeks
According to your picture above, the skin infection is relatively large. You can apply baiduobang ointment with growth factor. In the near future, don't touch water, don't eat spicy food and reduce activities. If it doesn't get better, it's recommended to go to the dermatology department for examination.
Depending on the situation, it is mostly caused by skin eczema, which will be accompanied by pruritus. You can apply pikangwang ointment after disinfection with Iodophor. Usually, do not contact washing powder, detergent and other chemicals. Take loratadine and Huangbai capsule for a few days. You should also pay attention to light diet and eat more fresh fruits and vegetables.
