Here are possible causes of headache and joint pains in a 4-year-old:
You can try to give your child 2 ml of calpol syrup 3 times a day and do tepid water sponging. This will help him recover soon. If he is not better after 2 days, please see a Doctor.
Also, see a Doctor if the fever does not go down with sponging or Calpol.
I hope this helps you. All the best.
