<s>[INST] Hi my son is three years old and for about three days he s been having an on and off fever of 101.6 and it s always right after he wakes up from his nap about noon. The fever goes away with children s Tylenol but returns the next day after the nap. And he complains about pain on his feet it seems like it hurts when he steps on them. Plz help [/INST] Hi...your son seems to be going through a viral illness. You are right in giving paracetamol. ITIS usual in viral illness to have body pains and especially of the limbs. But only thing which you need to look for is - his activity when there is no fever and if he is active when there is no fever, you need not worry. If the fever doesn't settle in another 48 hours or if his activity is getting depressed or if his limbs are getting a reddish rash kindly consult your pediatrician. Regards -  </s>
