Meningitis is an inflammation of the membranes (meninges) surrounding your brain and spinal cord.
The swelling from meningitis typically triggers symptoms such as headache, fever and a stiff neck.
Early meningitis symptoms may mimic the flu (influenza). Symptoms may develop over several hours or over a few days.

· Headache with nausea or vomiting
