Try not to scratch in future, but cool the itching down by washing with cold water, apply calomine lotion which you can get from the pharmacist. As a good home
remedy you can apply lots of
natural set yogurt to cool down the itchiness.
A doctor would prescribe the appropriate cream or ointment, antibiotic, antifungal cream or a combination of antifungal and antibacterial cream, depending what was causing the problem.
