Meningitis.

Sav

So I have had a headache since yesterday afternoon, and yesterday I noticed a little bit of a stiff neck, which has gotten worse. All of this is accompanied with nausea. When I looked it up the first thing I saw was meningitis. I haven’t checked to see if I have a fever which I don’t think I do.

Could it be something else other than meningitis and when should I go to the doctor to see if it is meningitis?
