I m a 12 year old female, and when I went to sleep I suddenly woke up due to severe stomach pain . I then started to feel pain in my legs. The next day I went to school and the morning everything was fine. I was very cold and shivering in the class when it was +24 degres outside. That night I was shivering so much and I was sweating as well. I shivered so much I had cramps. I had constantly increasing fever, severe headaches, a bit of a blurry vision , and I woke up at 3AM. I was very dizzy, and my legs were very week, I had to hold on to something to not fall. I then felt a need to vomit , but I drank something cold and everything was fine. I always have feelings to urinate. I also experienced joint and back pain. I also cough alot. We went to Mexico recently, could I have Malaria?
