Should injured limbs be kept above heart level?

Yes, injured limbs should generally be kept above heart level to help reduce swelling and promote circulation. Elevating the limb can minimize blood flow to the area, thereby decreasing inflammation and pain. However, it's important to ensure that the limb is supported comfortably and not in a position that causes additional strain or discomfort. Always consult a healthcare professional for specific advice based on the nature of the injury.
