hii.welcome to our site.i have gone through your question.my opinion is that, 1.dont scratch the lesion as it may worsen the condition. 2.maintain good hygiene in the itchy area. 3.apply clotrimazole ointment twice daily on the itchy area for 7 days. 4.take levocetrizine tablets twice daily for 7 days to control itching. thank you.
