I am really concerned that your son is suffering from headache and fever.
Fever due to infections can present with body pain
and headache especially viral fevers. Antipyretics like tylenol
helps in decreasing fever and headache. However he needs to be evaluated by a pediatrician
to ascertain the cause of fever and if needed antibiotics and blood tests can be added.
Rarely infections in brain presents with fever and headaches
. So it is always advisable to get a doctor's opinion.
Don't worry he will be alright. Give him adequate fluids , some amount of food and good amount of bed rest
. Take care.
