<s>[INST] my son is 7 and he has he says feels like sloshing in his brain he has nausea from time to time and he also told me just this weekend that he has a burning sensation on his arms and his face and his legs sometimes and that was right during the nausea so I m wondering what it could be [/INST] Hi...this could be type of migraine which the kid is unable to explain and express properly. Sometimes the symptoms of Migraine can be very non-specific like this. If there is a family history of migraine, all the more the probability increases. I suggest you give Paracetamol in the dose of 15 mg/kg/dose (Maximum 500 mg ceiling dose) every 4-6th hourly that too only if there is severe headache. I suggest not using combination medicines for fever, especially with Paracetamol. Regards -  </s>
