Hello, I suggest you go to a regular professional hospital in time for a good check-up, diagnose your illness and give you symptomatic treatment. If you find a rash and running water after scratching, don't use drugs indiscriminately. You should take the initiative to go to the hospital to see a doctor, consult relevant treatment matters, and confirm your illness. First of all, make an appointment with Nanning Fukang Dermatology Hospital (No.28 Anji Avenue, Xixiangtang District, Nanning). After getting the doctor's guidance, rational medication and symptomatic treatment can be restored as soon as possible.
