My son is four years old and complaining of leg pains.After that he gets a very high fever and complains about his head paining which brings him to tears.Also his nose starts running but the fever gets worse in the night time.What is the cause of thins please advise ASAP.
Leg pains with fever is something serious and that too if it recurs and goes on he needs to be investigated. If it's a single episode, it could be a viral infection with myalgic and with simple paracetamol, he will be alright.
