A baby with all symptoms has white blisters all over the mouth, fever of 38 degrees, drooling, and crying while eating. On May 1, 2010, the baby had white blisters in the mouth while eating and drinking, crying in pain. What should I do? The primary consideration is herpetic gingivostomatitis. It is mainly caused by viral infection and can be complicated by bacterial infection when severe. Hand, foot, and mouth disease mainly occurs in the throat, palms, soles, and occasionally on the buttocks with rashes. Oral ulcers refer to damage or defects in the oral mucosa. Guidance: It is recommended that you take the baby to a local hospital for routine blood tests and have the doctor examine the mouth, palms, and soles as soon as possible. After an accurate diagnosis, choose a reasonable treatment plan and seek medical attention promptly to avoid delaying the condition.
