Question
Why does a 4-year-old suddenly have severe thigh pain and refuse to walk?
Answer
Hello, the possible causes of a baby’s leg pain and refusal to walk could include calcium deficiency, growing pains, or overexertion from playing. It is suggested that you take your child to the hospital for a trace element test to confirm the diagnosis and take appropriate treatment measures. If diagnosed with calcium deficiency, consider giving your child Longmu Zhuanggu Chongji, a traditional Chinese medicine preparation, which has good absorption and does not require additional vitamin D.
