Is this from rubbing or to large of meal?

The areas in question are the greyish reddish ones. Almost like bruises or something. None of my other snakes have this. The spots near the mouth look like just the butter coloration and of no concern. This butter female shows no signs or issues of anything eats great, growing well and shedding fine. Just noticed these areas on her and I assume they are from her trying to get out from time to time or from a large meal i gave her couple weeks ago. Any thoughts would be great just want to make sure its nothing to worry about. Thanks!

It's just from rubbing against the enclosure. Nothing to worry about.

Thanks what i figured!
