i've had an lumber puncture before... lets just say its not the coolest thing to have done to you out there!!
Meningitis is serious but its not that easy to catch. The chances that you have it are slight, but if you have any of the symptoms, then you should have yourself checked out. the symptoms are stiffness in the neck, photo sensitivity, sensitivity to loud noises, a constant headache, dizzyness, nausea...
I hate when people give symptoms like this. Remove the stiff neck and I've got all those symptoms, but I know I don't have meningitis, those symptoms are part of ADD as well
