<s>[INST] My son is two years old. His head, neck and hands feel really hot but according to the thermometers (I used different ones to make sure it wasn t caused by a faulty reading) he does not have a fever. Additionally he has a rash on his hands, both the backs and the palms and he often complains of stomach aches. What can be causing all this? [/INST] Welcome to the Chat Doctor I understand your concerns. Child Chat Doctor.  This happens due to poor regulation by temperature control centers in brain I.e. Hypothalamus. Don't worry as it improves on its own by 5 years of age. As far as the rash is concerned, I will be able to guide you in a better way if you post me his photographs as direct query. Hopefully this will help you. I will be happy to help you out in any child related questions. Take care </s>
