Is now at University! :D
I put a green ring around the mark on the second photo to make it easier to spot on the first one. (Although it\'s pretty obvious)
The mark remind me of a blood blister, such as when you catch your finger in a door or something.
It\'s below the skin, there is no raised bump or any other signs of ill health.
Could it be that it\'s bumped it\'s head at some point?
Do I just observe and wait for it to go away?
Thanks
