What are the symptoms of hand, foot, and mouth disease?

Patient's question:

The baby hasn't been eating much lately and prefers to play with spit. Yesterday, several blisters appeared on the wrist and ankle, and I thought they might have been burned. When eating, I noticed blisters in the mouth as well, like oral ulcers. After checking at the hospital, the doctor said it was hand, foot, and mouth disease.
What kind of help do you need: What are the symptoms of hand, foot, and mouth disease?

Doctor's answer:

Guidance: Hello. Hand, foot, and mouth disease manifests as an acute onset with fever; scattered vesicles of rice-grain size appear on the oral mucosa, causing significant pain; vesicles of rice-grain size also appear on the palms or soles, with the buttocks or knees occasionally affected. The vesicles have an inflammatory red halo and contain minimal fluid. Some children may also experience symptoms such as cough, runny nose, poor appetite, nausea, vomiting, and headache. This disease is self-limiting, and most cases have a good prognosis, with full recovery typically occurring within one week without leaving any. In rare cases, it may lead to severe complications such as meningitis, encephalitis, myocarditis, flaccid paralysis, or pulmonary edema. Currently, there is no specific treatment for this disease, and general symptomatic treatment is usually administered.
