<s>[INST] I have a 6 year old female that has fever and headache for just over a week now. Headache that makes her cry and wakes her up from sleep. He fever is off and on and usually around 101. Her doctor found nothing wrong but did blood work that came back fine. Strep test came back negative. She is getting a molar. Her dad thinks she has allergies and gives her claritin while at his house, but she doesn t show what I think are normal allergy sings ie: watery eyes, runny nose, congestion [/INST] Hello. Thank you for asking at Chat Doctor. I would suspect some infection if your daughter has fever and headache for a week, rather than allergy. Most of the infections are viral, they need rest, plenty of fluids & treatment for symptoms. They recover by themselves. So if your daughter does not improve with suggested treatment by your doctor, I would suggest you to consult your doctor again, who may suggest further investigations to rule out other infections. Hope this was helpful to you. Wish your daughter the best recovery. Regards. </s>
