Hi, I just got done holding my brother's ball python and noticed it has red spots under it's head and about an inch down it's 'neck.' I know that this is not normal and am very worried about it!
What could this be from? Any ideas? Please help, thank you!

Also, the ceramic heat emmiter just got placed in the cage because it was not making it hot enough - the cage is very tall. The snake sometimes climbs up to it, only to try and get out - there used to be hole. When it is up there, it is moving fast and trying to get off of the heat and quickly gets off of it...could this be the cause of the red spots? (also her whole belly is kind of pink - not because she is shedding, she just got done.) Will she learn not to climb on the heat emmiter? Or does it need to be taken out and an alternate method of heating used to get proper temp? Thanks!
