Interestingly, reading up on sensory integration disorder - DD has high pain threshold. As a baby/toddler etc my friend mention once that she wondered if she had issues with not feeling pain, as she hardly ever cried when she hurt herself. She did cry if it actually hurt badly, if it was a proper cut or bump etc, but she would not wing at all if she bumped her head quite hard, she would just get up and carry on, it was not like it didn't hurt, but that it was not important. She is actually less like it now, I think partly as she has a younger sibling so gets that if it hurts she gets a fuss! But, actually, when she whines I know she is not that hurt, when it's a bump for real she actually tends to be less bothered. She was not hugely distressed when she broke her wrist, it hurt, but she was very 'brave' and didn't cry particularly hard i did and had the bones pushed back in place with gas and air only. Everyone always things she is a tough cookie as complains so little but, perhaps it is something, although not the condition my friend was thinking of.
She also isn't always hugely bothered by cold or heat, but not always, it's more that she is pre-occupied so doesn't pay attention. She usually does later, like at the beach yesterday, she went into the sea and I had to ask her to come out as she was shivering, and her fingers had gone numb. She had not noticed until she was sat down and dry and one of her fingers was still numb and she didn't like it (it was fine, just took some time to warm up). She got cold today without a jumper on though, and told me so, so it's not always.
She has no coordination, her gross motor skills are not fab at all, like kicking a ball, but she can ride her bike, swim, etc, and her fine motor skills are fine.
Interesting to read it all! I expect to manage any sensory issues that are leading to her climbing of things, on things, over things, swinging off things etc, we need to manage as said already. I don't think it's necessarily something that needs a 'diagnosis', but it's useful to use the information to help manage it.
