BLUE TONGUE SKINKS

Hi everyone, my Halmaheran blue tongue skink who I believe is a female has a very chunky neck. I have not felt it as she is very skiddish but is this normal? Perhaps she is just overweight?

Update: I felt the lump and it feels not hard, but not exactly squishy either, it feels as if it has some bounce to it. More squishy than hard though.

So the question is this a lump or just her natural chunky neck. Compare both sides of her neck. If she is equal portions on both sides then it is normal chunky neck. If not, then it is a lump that need to be evaluated. Hope that makes sense.

Also I just wanted to make it clear that some skinks have just normal chunk necks.
