Baby had stomach bug. I have had temp around 100 for 2 days and my neck is a little stiff but could be from pillows. Could this be meningitis?

Meningitis. The only way meningitis can be diagnosed is with an assessment by an MD with a lumbar puncture. So if you think you could have meningitis see a doctor now. It is a much too important to miss. I hope you have good health.
