What tests should be done if you often have knee pain?

Patient's question:

Sore knees when going downstairs during the day, not sore at night for 1 week

Doctor's answer:

Analysis of the condition: Hello, for your situation, you can choose to have imaging tests. If there are no bone issues, it might still be considered a calcium deficiency, and it can be taken orally for a longer period! Suggestions: It often occurs after dinner, massage and heat application can help relieve it. During the day, if the child's activity level is high, after some time, you will find that the child's height grows relatively fast during this period. When he first experienced this, I suspected it was growing pains, but I still took him to the hospital for a check-up to confirm it. It is recommended to have a trace element test.
