My daughter 14yrs has bruising under her left eye and check. It is very noticeable and I was very concerned as she has not had an injury. I took her to the local drs who ran some blood tests and everything appears to be OK. the dr has said that she thought it could be an aneurysm on the cheek and that all should be OK.
Bruising is definitely injury, unnoticed and sometimes finger nails of the baby cross-over eyes and injure; aneurysm is something not heard of in that region except some nevus which should have been present since birth.
