DD (2.5) has had a fever of 38-39 all weekend. It comes down to 36 after neurofen. She has no other symptoms. On googling (oops), it suggests a UTI if no other symptoms...or could it just be a virus? Should I get her to OOH dr today or do you think it can wait until tomorrow? She is fine in herself as we are keeping the fever at bay, but I am still concerned that it keeps coming back.
