Question

My son found one of his hands slightly swollen when he woke up this morning. What could this be? He has always been very healthy, never taken any medication, and never been injured.

Answer

Upon waking up, if your child finds their hand swollen, it’s important to first check for any signs of injury, such as a bruise, and ask if they have had any falls or collisions. If there are none, consider whether the sleep position might be a factor; for instance, sleeping on the same side for a long time could compress the blood vessels, leading to poor blood circulation. If the swelling is not severe, you can continue to observe; however, if the swelling is significant, it is recommended to see a doctor for further examination.
