A mum has shared how her teenage son is so allergic to the cold that they have no choice but to blast the heating all day long to keep him safe, and drive him to school rather than risk letting him walk.
Calum Courtney, 14, has a condition known as cold urticaria, which means he can't be outside for more than 15 minutes without getting itchy, red rashes.
His allergy is so severe that he breaks out in hives if the temperature drops lower than 24 degrees or if one of his limbs is left dangling out of his bedcovers at night.
