Hi, I didn't think I was going to write, but I'm starting to worry, and I have a lot of questions. I have had a rash just above the knee for about a week. Represents many small red "pimples" in the form of a circle with a diameter of about 4 cm! I wonder that they are only in this place and form exactly a circle! I smeared them with "Health" cream and the pimples in the middle of the circle faded, but the skin began to whiten. Those on the edges are red and itchy. If I'm wearing pants longer than the knee, I don't feel itchy, but if you lift it, it starts. What could it be? An insect bite? Alergic reaction? Or maybe it's even from the razor, but it's in exactly the same place? Girl, 15 years old
