Simplest answer: ask your doctor. (If only we all had kindly, knowledgeable doctors who knew us personally).
Simple answer: whether or not you have meningitis, if you feel that sick you probably need treatment for something. Get offline please, and call 911.
More complicated answer:
The symptoms you experience vary depending on your age.
Older patients and those who care for them should be aware that meningitis can give other symptoms. In more severe cases, patients may experience problems with speech or hearing, double vision, hallucinations, personality changes, loss of consciousness, loss of sensation in some parts of the body, muscle weakness, partial paralysis in the arms and legs, sudden severe dementia, impaired judgment, seizures, and memory loss. Hopefully, if any of these occur patients will contact medical personnel. But do mention if the person had a severe headache and a stiff neck to aid in diagnosis.
