I believe something similar to this happened to me at a military hospital when I was just 13. I had severe symptoms including stiff neck, high fever, incredible drowsiness and malaise. The military doctor diagnosed it as “muscle spasms.” I was sick, with continual relapses, for about a month, but eventually fought off whatever it was. To this day I wonder whether it was meningitis.
The same thing happened to me when I was a teenager. I had stiff neck, severe headache, extreme sensitivity to light, was extremely weak and sick, and had a slight rash. The doctor said I had the measles, even though my stepmom and I both remembered my having the measles when I was younger. I was out of school and severely sick for weeks. A few years ago I read about meningitis and recognized the symptoms.
