My 9 year old otherwise healthy daughter was checked for a UTI about a month ago - but her urinalysis showed she did not have one. Now this weekend she again has urinary frequency and urgency (but no burning or pain), as well as headache, dizziness, stomach ache at times, appetite comes and goes (but no nausea), no fever. I m bringing her in to see her doc today , but if this is not a UTI - what else could it be?
