What condition does 'claudication' refer to?

Claudication is a term specifically used to describe pain, discomfort, or cramping that occurs in the legs or buttocks during physical activities, such as walking or climbing stairs. This condition is typically brought on by insufficient blood flow to the muscles, often due to arterial blockages. The key aspect of claudication is its association with a feeling of lameness or limping, as the discomfort usually resolves with rest. Understanding this term is important in the context of vascular health and can indicate underlying circulatory problems.

The other options do not accurately describe claudication. Loss of muscle mass pertains to atrophy, joint swelling relates to conditions like arthritis, and throat irritation is associated with different medical issues, none of which are indicative of claudication.
