What could be the cause of knee pain in a 4-year-old?

Question

Hello doctor,

My son who is turning 4 in two months, has been complaining about pain in his knee for over a year now. His pediatrician told us that it was growing pains and was normal. However, it has been there for too long and it is always just the right knee. He cries at different times of the day about his pain, mostly at night and after school.

He holds on to his leg right under his chin, cries, and does not let us touch him. Some nights he cries himself to sleep from the pain. There is no swelling, bruises, redness, or anything in his knee that looks or feels abnormal. What could it possibly be? Which specialized doctor should I take him to and what tests should I expect him to do?

Please advise.

Thank you.

Hello,

Welcome to icliniq.com.

I think his knee pain is of significance since it is involving only one limb, and it has been so for quite a long time. Sometimes, there may be a hidden bone infection which may go unnoticed.

It is advisable to do an X-ray of the affected leg, and take an opinion from an orthopedic doctor who will be able to examine his leg thoroughly.

I hope that you get your answer.

Please let me know if you need any help.

Thank you.
