What could cause low grade fever and headache?
Patient: My niece is 4 yrs old and has a low grade fever and a headache. She has been to the doctor and is on amoxicillin. She started out with a headache, then a low grade fever that escalated to 105 and vomiting. My concern is she has been on antibiotics for 2 days, she was tested for strep throat and that was negative. What could be causing the headache? Doctor: Hi,  Does she have abdominal pain or loose stools? Fever, headache and vomiting is most likely from a viral fever.  Let her take some rest, take paracetamol 3 times daily even if afebrile(for headache) and drink plenty of fluids in small frequent sips.   This will subside in 3-4 days. Nothing to worry if she is otherwise playful and taking feeds.  Get back to doctor if fever does not subside by then, headache is sever or vomiting persists.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr. Muhammed Aslam TK
