Red rash on my thigh—what could it be?

Hi there,

About a month ago, I noticed this reddish spot on my upper thigh—maybe 2cm long and about half a centimeter wide. It doesn't bleed or hurt if I touch it, but the edges look a bit rough, almost like scabs...
I figured I just bumped into something and didn't think much of it, but then I noticed today that it hasn't gone anywhere—which is starting to worry me a little.
I've attached some photos so you can see what we're dealing with... any thoughts?

Thanks,

Just go see a doctor, honestly. You'll probably just walk out with some prescription cream. If that doesn't do the trick, they'll send you to a dermatologist. 🙂
