Hi Doctor, I am 25 male 6 ft tall. I have some infection in my my groin area ( at inner thigh). Initially I though that probably it was an insect bite as it itched the same way but later a few more spots grew which are circular n shape. Together they form a line and are separated by very small distance around 5 mm. they look like as if i had scratched an insect bite but a little large in circle. I also feel extreme sense of itching in my scrotum once once i rub my balls.
