<s>[INST] Hi i m 15, 5 3, and i m anemic and have low white blood cells. Every since i went on a school trip a couple weeks ago, everyone threw up including me but they felt better afterwards. But i keep feeling nauseous and throwing up occasionally. Is this normal? [/INST] Hi,As has been going on for a couple of weeks, It cannot be attributed to the same food poisoning which might have occurred two weeks ago to your colleagues. I feel that this might be an acid reflux. I suggest you consult your pediatrician regarding this.Hope I have answered your query. Let me know if I can assist you further. Regards,Dr. Sumanth </s>
