Patient's question:
The baby, who is only twenty days old, seems to be frequently startled to the point where his hands, feet, and entire body tremble. Treatment history and effectiveness: A few days ago, he received the high-dose hepatitis B vaccine. What help is needed: I would like to ask the doctor for some assistance in resolving these concerns.Doctor's answer:
Now the baby is still small, the brain's growth and development have not yet improved, and its functions are not fully mature. In contrast, the lower brain centers and spinal cord have already surpassed a more developed functional level. Therefore, the movements of newborns are mainly completed through subcortical centers such as the spinal cord. They are not completely suppressed by the cerebral cortex, so there are often purposeless, involuntary tremors in the limbs. Thus, trembling in newborns' limbs is a normal physiological phenomenon and has nothing to do with convulsions or calcium deficiency. As long as they don't cry frequently, there's no need to worry. It will improve as they grow older. However, if there are other accompanying symptoms, it is necessary to consult a doctor.
