the red spots only appears when you scratch, for myself i think is because the weather in UK is dry, or the place where I live got some small insects which bites, I live in Greenwich. This has never happened to me before
Also is only appears does places where I sweat a lot
for body i mean inside hand and finger, stomach, back, legs, arm, armhole, up to the neck.
I shower two times a day, regulary so i dont know whats wrong, I eat healthy aswell
