If your daughter has been developing bumps on her back for the past 3 days, it is important to monitor her symptoms closely. Since she is not experiencing a fever and the bumps are localized to her back, it may not be a cause for immediate concern. However, if her condition worsens or if she starts to show signs of infection, such as fever or discomfort, it would be advisable to seek medical advice from a doctor. In the meantime, you could consider visiting a pharmacy to seek guidance on potential treatment options based on the pharmacist's assessment.
