Question
A child is experiencing knee pain that has persisted for some time, and parents are concerned. They hope to receive medical advice.
Answer
Hello: For children around 3 years old, if they experience knee pain, even limping, the next morning after a cold or intense activity, the cause may primarily be viral stimulation after the cold and excessive hip joint mobility leading to hip joint synovitis, which then causes pain on the inner side of the knee. This condition usually heals naturally with rest for 2-3 weeks. For children over 10 years old, if they are very active, they may experience pain after rest due to increased knee pressure or due to rapid growth causing growth pain. In these cases, simply ensuring adequate rest is recommended.
