My daughter has a scab on the back of her inner thigh, close to her vagina . It is in the shape of a circle & it us about the size of a dime. I noticed it last weekend & tonight I noticed a few more on her butt. At first I thought it might be a burn , but that didn t make sense. My second thought was that it was a bug bite , but it s not going away. The spot hasn t gotten worse, but it hasn t gotten better either. It s been about 9 days since I first noticed it & now there are more of these spots.
