I get this also.
Have not asked any of my docs about
it but had one recently on my inner thigh.
It is mostly gone now but I can still see a red spot kind of like a scar.
It does not bug me so I don't give it much of attention, I only notice this spot because I can see it every time I go to the toilet
If you have yours checked out it would be fun to hear what it is ;)
