my 7 yr old daughter has had a cough for over a week with no ther symptoms except runny nose . The doctor checked her out and said she was fine except the usual allergy stuff. she has no fever but now shes been feeling dizzy, has a bad headache , and eyes hurt all within several hours. this has to be more than allergies, correct? but no panic because no fever, correct? what could be going on? take her back to doctor? blood work? thank you in advance!!!
