Think I had meningitis 10 years ago, now what?

Hi

While I was a student I got ill. I had had chronic sinusitis since childhood.
Confusion, agitation, sweatings, feeling of unreality and much more when I got seriously ill. Now it has been 10 years since that but I am still sick. When I eat candy I get like razor cut sores on my forehead. I have read some about meningitis and I think I might have had that. How can I know for sure? Is it possible to diagnose with MRI or lumbar puncture after such a long time? Tweet
