What should I do if my baby, who is nine months old, developed a water blister on the thumb yesterday?

Patient's question:

My baby is nine months old and had a water blister on her thumb yesterday, and another one grew last night. What could be the reason and what should I do? Thank you for your assistance. What kind of help would you like: Could it be hand, foot, and mouth disease? What kind of medicine can she take? Thank you.

Doctor's answer:

This friend, please don't hurry. If the baby doesn't have a high fever, then there's no need to worry too much. Even if it's hand, foot, and mouth disease, without a high fever, it's relatively easy to treat.
Advice: If there are blisters locally, it cannot be ruled out as hand, foot, and mouth disease. For now, antiviral medication can be used for treatment, such as acyclovir ointment for topical application. Additionally, go to the hospital for a check-up to diagnose the condition, and then actively treat it accordingly.
The above is the advice for the question "My baby is nine months old and had a blister on the thumb yesterday." I hope it helps you. Wishing you health!
