A pharmacist cannot diagnose an ear infection in a child. This diagnosis is typically reserved for medical doctors. If your child is experiencing ear pain, it is best to consult a doctor or pediatrician to determine the appropriate treatment. If the pain increases when you pull the ear lobe back or open the jaw, it may be an external ear infection. In this case, antibiotic drops may help alleviate the pain. However, if the pain does not change with these actions, it could be a middle ear infection, which requires a doctor's prescription for antibiotics. It is important to monitor your child's symptoms and seek medical advice if needed.
