Question
A 7-month-old child suddenly has a bit of twitching, with symptoms including involuntary movements of the upper body, resembling chills. Even after being kept warm and exposed to sunlight, the condition does not improve and persists for a week. What could be the cause, and do I need to seek medical attention?
Answer
The child may have vitamin D deficiency, leading to elevated neuromuscular excitement and causing hand and foot tetany. It is recommended to bring the child to the hospital for a check-up on trace elements and vitamin D levels as soon as possible. You can go to the maternal and child health hospital or consult pediatric outpatients. Wishing the child good health!
