Does anyone know what these marks are?

[Ausmar]

Does anyone know what these dark circle marks are on my inner thigh? They have been getting bigger. They are flat with no texture, never itchy or sore. Curious to know what it may be so I can try and treat or prevent from getting bigger.

Are they stretch marks? Hard to tell.

They are uniform and matching so I’d be nearly sure they are from an external pressure.

You haven’t started a spin class by any chance? Or using some gym equipment recently? Or have a new saddle on your bike?

The dark spots, or the lines?

The lines are stretchmarks. The spots, yeah, I'm stumped. They're on both thighs, so a bruise?

I don't mean to imply, but it might suggest clamping your legs closed around something hard and spherical in that spot. I'm guessing this isn't your first time looking there, so not birthmarks.

Could it be ringworm? I used to get it there every time I was run down, but not both sides.

The lines are stretch marks, but the 2 dark circle marks I’m really unsure how they appeared, no cycling, gym classes etc.

I think they appeared about 1 year ago.

Looks like ringworm.
