Brief Answer: Details below Detailed Answer: Hello Thanks for the follow up. Blisters are usually on outer lip in herpes, however it can even present with blisters limited to inner lip and throat occasionally. The manifestation in toddlers is quiet different when compared to adults as their immunity is low. Fever was the main concern. If the fever has decreased you don't need to worry much. These oral and skin lesions will heal within a week as it seems a viral. Let me know if you have any other doubts. Thank you
