Aspergers and pain thresholds

[Shugarlips]

My son (5) broke his arm on holiday and didn't cry once.

When he was younger he shut his finger in a door and the finger nail went back - didn't flinch.

He has only screamed in night terrors so I don't count that as crying and sobbing.

He didn't even 'properly' cry (I mean like my daughter)when he was a baby.

He had terrible tonsilitus before he had them out - never cried or appeared distressed at being ill (apart from having a temperature). Also when he has had stomach upsets he just gets up, is sick and goes back to bed or goes back to what he was doing - no distress as such.

I guess what I am asking is do children with AS have higher pain thresholds?

DS had very high pain barrier when he was a toddler, did not cry at all if he hurt himself, we only knew from the bruises that he got hurt. He lost his big toe nails at least three times and carried on as if nothing happened. However, he is a completely different boy now. For the last six months, he cries at the tiniest pain, will come to show us that it's hurting and tries to milk on the situation by crying more to get things his way. His pain threshold is definitely lower as we see him flich if he brushes past something.
