rash on thigh?

it’s small, about an inch long, not itchy, and sometimes is really dry with skin flaking off even if the area around it is perfectly fine. texture is rough to touch. hasn’t changed size at all since it popped up. it’s my upper thigh halfway between inner thigh and the top of my thigh if i was sitting down(in case it matters) i’ve had eczema my whole life so i don’t believe it’s that. i also had something called fifths disease that was triggered by the eczema when i was a kid if that is important at all. i wouldn’t even care usually but it hasn’t gone away for 3 weeks now.
