If my child has fever over two days, I usually go to see doctor. You know, just in case. It's better than you worrying more and more and don't know what's the right thing to do.
me guess your daughter's fever has nothing to do with what the doc took from her ear. she just checked to see if she had infection in the middle ear; apparently she did not.
a fever usally takes 5 to 7 d to subside; if no rash or toxicities, no big deal
