My 5 yr old awakend this morning feeling warm. After checking his temperature (armpit) it was around 100f max. He is drinking fluids but does not want to eat. He said he had a headache and wanted to sleep. Before that he said he was feeling dizzy. He was able to walk to the bathroom on his own without falling down. He never has headaches accompanied with a possible fever or dizziness. Should I be worried of possible meningitis?
