Looks like rot, insect, or rodent damage. Did you let the tortoise hibernate outside in a burrow? Or inside in a fridge?
No I am not.
He was inside.
Do you know how I can prevent this in the future. He also has some in the front by he's toes.
How large was the container or box in which the tortoise hibernated? If it was too small, it might be that these spots are skin abrasions from the tortoise pushing up against the sides of the container. To prevent this, you should use a box or container that is large enough so the tortoise cannot get traction with its back legs against one side or end and push itself forward against the other side of the box.
It was plenty big when where he was able to move it was a tote. Do know if tortoises shed? I was doing research and came up with this as a possibility?
Ok so just treat it with some neosporin should clean it with anything such as soap and water first
