Question
A parent inquired about their daughter, who has been frequently complaining of knee and ankle joint pain since she was 4 or 5 years old, especially on days with physical education classes. The parent took the child to the hospital for examination, but no obvious issues were found, and a rheumatoid blood test was conducted, with normal results. The parent wants to know the possible causes of this pain and whether additional examinations are needed.
Answer
Knee and ankle joint pain in children aged 4 to 5 years can be caused by a variety of factors, including injuries, deficiencies in trace elements, developmental abnormalities, growth pains, and transient synovitis. It is recommended that parents further check the child’s levels of trace elements to rule out related causes.
