Ds is 11 and very skinny. Now the weather has turned he constantly complaining of being cold. He wears a thermal vest, shirt, school jumper, blazer and down coat to school but comes home freezing. He is active and never still. He has a rugby tournament at school tomorrow during school hours and will be outside for 3 hours. He won’t be allowed to wear a coat even when he is not partaking and he is dreading it. It takes his colour and he looks drained when he gets cold and makes him feel poorly. Is there any medical that make him feel so rough
