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-antigen hepatitis B vaccine. What help is needed: I would like to ask the doctor for some assistance in resolving these worries and difficulties.Doctor's answer:
Now the baby is still young, and the brain's growth and development have not yet improved, with its functions still not fully mature. In contrast, the lower brain centers and spinal cord functionally surpass a more developed state. Therefore, the movements of newborns are mainly completed through subcortical centers such as the spinal cord, which have not been fully suppressed by the cerebral cortex. As a result, there are often purposeless, involuntary tremors in the limbs. Thus, tremors in newborns' limbs are a normal physiological phenomenon and have 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's necessary to consult a doctor.
