Had a sore neck, headache and fever last week. Still have a headache sometimes. Scared its meningitis, do symptoms just go away or was I just sick?

Vague. Need to call the Dr. you are seeing to help provide answers. Need to know what a thorough history and type of headache.
No way to tell. You need to be seen and examined in order to exclude specific diagnoses. If you ever suspect that you may have meningitis you should be seen asap. Do not delay, go to doctor and provide full history.
