Hi I have a 6year old dc and for the last 5 days he's had a temperature but only in the evening from about 5pm. He gets lethargic and sits down after about this time. He also has a slight blocked nose and has one very wobbly tooth! Would those cause this? I don't understand why he would only have a temp in the evening and not all day. He is fine during the day running around and playing. Has anyone else had this? Should I take him to the Drs tomorrow?
