What are these?

Hi i have an EE who has some welts i guess on her leg, they have a texture of a minor burn. I know its not an actual burn because we dont have any live heat sources at the moment. I was wondering if anyone knew what they are

That's interesting.

I don't know what it that may be. Is it just the one spot on the upper leg?
The lower area looks like a spur bud.

Could be from an injury. It's something I'd just monitor and if there's any changes, then let us know.
