Question
A four to five-year-old child frequently reports pain in the knee and ankle joints, a symptom that has been present since kindergarten. The pain becomes more frequent on days with physical education classes at school. Hospital examinations have not revealed any abnormalities, and rheumatoid blood tests have also been normal. What could be the possible causes? Is it necessary to undergo other examinations?
Answer
Frequent knee and ankle joint pain in children between the ages of four and five may be caused by factors such as trauma, deficiencies in trace elements, developmental abnormalities, growth pains, or transient synovitis. Therefore, in addition to the exams that have already been conducted, it is recommended to undergo trace element testing to rule out related factors.
