This happened to me 10 years. Before, I was a teenager, and the sister of my adoptive mother took us to the ceasefire. I became ill with symptoms described, and have sat down and the sister of my adoptive mother only, and I suffer the whole time and I did not see the doctor, now that I'm 25 and I think I could die or could have meningitis?
