I have a low fever (99-100.5) starting yesterday, and yesterday the back of neck kind of hurt when I looked down (it still does today, but it's better). I have no other symptoms besides the headache/dizziness associated with a fever, no coughs, runny noes, etc. I read that these are some symptoms of meningitis, but my symptoms seem a lot less severe that the ones I have read about. Is there anything to worry about?
