<s>[INST] My son who is eleven has what I think is a stomach virus. It started late last night and every 1 to 1 1/2 is stated vomiting . He stopped vomiting at 6am but now he has stomach pains and headaches which I m giving him children s pain relief for headache. Is drinking a little Gatorade and eat 2 salten crackers. Have a little diarahia. Please give me advice. Thanks [/INST] Hi He is suffering from Gastroenteritis. As he is having vomiting,tablets will also be vomited. So,it is better to admit him and give him injections and intravenous fluids. He will recover Wish him good health and  speedy recovery Regards </s>
