Welcome to Health Care Magic
It should be taken as allergy
to the antibiotic, if it occurs while on treatment... But it is 10 days already and the child also has fever
- fever is not from allergy..
This may mean there is some other infection? usually, not necessarily, viral...
Give the benefit of doubt / stop the drug / and consult the doctor...
Recurrent UTI in a child needs investigation / generally the problem is congenital anomaly
is the concerned specialist...
Wishing speedy recovery
