Help painful Temperature Sensitivity

Does anyone elses child have pain when they are too hot?

My daughter appears to be undersensitive to cold but suffers from extreme, painful 'prickly heat' when she transitions from a cold to warmer environment.

Eg playing netball on the school playground then going inside to lessons will give her painful stabbing sensations in her legs which she describes as worse than a migraine.

Any help or advice in how to manage the pain would be appreciated.
