Is this the initial symptom of hand, foot, and mouth disease?

Patient's question:

Spirit, appetite, food intake, sleep, and everything else are normal, only visible red small spots under the subcutaneous tissue of the palms. Today, it was discovered, but the specific cause is unclear

Doctor's answer:

Hello, hand, foot, and mouth disease often starts with fever, cough, runny nose, and drooling, similar to upper respiratory infections. Some children may also experience symptoms such as nausea and vomiting. When hand, foot, and mouth disease occurs, the affected child often begins to develop a fever, with varying levels of intensity. Some people may not have a fever, but most of them are in the low-grade fever group, accounting for about half of the total. It is often accompanied by symptoms such as drooling, runny mouth, oral pain, sore throat, and anorexia. Clinically, blisters on the mouth, hands, feet, and soles are the main features. At the same time, in the mouth, such as the lips, tongue, oral mucosa, and gums, there are scattered blisters. However, the blisters in the mouth will rupture quickly, forming grayish-white spots or grayish-white membranes, with a red border. Under the membrane, spots or patchy erosions can be seen. If your baby does not have any other symptoms, it is usually not hand, foot, and mouth disease.
