<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi there. My 12 year old son had severe dizziness and headache all Saturday and Sunday and slept a lot. That has subsided but now he has a rash and sore throat. He seems fine though otherwise. Energy, appetite etc.Could the rash be from a weekend fever?  <response>: HI, thanks for using Chat Doctor The rash is likely linked to the symptoms that he experienced over the weekend and is continuing to have sore throat. The rash may be a viral exanthem which is a rash that occurs with a viral illness. It is common particularly in child Chat Doctor. He can use symptomatic treatment only treat particular symptoms present e.g. if itching- antihistamine, if painful- a painkiller etc hope this helps
