<s>[INST] My 8 year old has had a low-grade fever (between 99 and 101) for 6 days and is coughing a lot (hear it in his chest) - I took him to the doctor on Monday, and they said it must be viral. He is still feeling poorly. He has a stiff neck - could have slept on it wrong - but I don t know. Should I be worried or keep giving him Tylenol to manage temp? [/INST] Hi,It seems that he might be having viral infection but after 6 days still it persisted, there might be having chance of bacterial infection as well.He might require one course of antibiotic for 3-5 days.consult your doctor and get him examined again.Give him light diet and plenty of water.Ok and take care. </s>
