<s>[INST] My 5yr old has a fever of 101.4... he said he had a headache last night and a sore leg and went to sleep... he was restless and rambling nonsense in his sleep all night and kept waking up ... his temp is still 101.4 and now has a headache and both legs are sore should i take him to a doctor? [/INST] Hi, Thanks and welcome to Chat Doctor. It looks like infection may be viral. Paracetamol 15 mg/kg body weight per dose every 4-6 hourly along with tepid sponging depending on the necessity will reduce fever headache as well as sore legs. If no benefit within 48 hours better consult your doctor. Hope this reply is OK for you. PLEASE FEEL FREE TO ASK FURTHER QUERIES IF ANY. Chat Doctor. V. Subrahmanyam. </s>
