Question
Could my son’s big bubble in his mouth be hand, foot, and mouth disease?
Answer
The big bubble may be caused by herpetic gingivostomatitis, which typically starts with a viral infection and may lead to bacterial infection later on. It is advised to take your child to the hospital for a routine blood test to determine the infection status and decide whether symptomatic anti-inflammatory medication is necessary. Parents should closely monitor their child’s symptoms and help them seek medical attention promptly.
