Hi,
My daughter has two mosquito bites, and got a big reaction on the site of the bites - some swelling and a lot of itchiness. Just a day after, it looks like there is a black crust on the surface. Is this normal healing? i am worried about the black appeareance but it doesnt look skin deep and i know old blood can look black, but whenever she's had open skin lesion before, it heals brownish or redish-yellowish.
