My daughter is 17. Seemed to be very healthy, in the passed year she had done some regular tests and checkups (she was an elite athlete), including thyroid check and regular blood check - test were fine.
For the passed 3 days she has been sick. With the symptoms that at first we consider stomach flu: sudden vomiting few times a day, abdominal pain, maybe very low fever. Now she explained that her body was aching prior and feeling, tension in muscles and neck... nauseous... abdominal discomfort.... those were her first symptoms, then she started to vomit. Tonight she said her back was actually hurting for a few days and now her left side is in pain. She is vomiting and drinking Vitamin water to replace electrolytes and loss of body fluid…her left chest also have some pain.
