Why are blisters still forming after two days of treatment?

Patient's question:

Two days hand and foot mouth sores

Doctor's answer:

The symptoms of hand, foot, and mouth disease are a set of clinical manifestations caused by a viral infection, primarily characterized by fever, oral ulcers, and blisters on the hands and feet. Generally, it can be recovered within 7 days, so there is no need to worry. When there is fever and other clinical symptoms, symptomatic treatment can be applied.
