What term describes pain or tiredness in the limbs due to inadequate oxygen supply?

The term that specifically describes pain or tiredness in the limbs due to inadequate oxygen supply is claudication. It typically occurs with physical activities like walking or exercise, where the muscles demand more oxygen than what is delivered due to reduced blood flow, often as a result of narrowed arteries. This is why individuals with claudication may experience pain or heaviness in their legs, which improves with rest.

On the other hand, lymphedema refers to swelling typically caused by a blockage in the lymphatic system and does not specifically relate to pain or tiredness due to insufficient oxygen. Ischemia describes a condition more broadly related to inadequate blood flow and oxygen delivery to tissues, but it is not limited to pain or tiredness in the limbs. Similarly, heart failure involves the heart's inability to pump effectively, which can lead to numerous symptoms but is not directly synonymous with the specific type of limb pain experienced in claudication.
