A common clinical feature of temporal arteritis is jaw pain with chewing, also known as jaw claudication. Which option best describes this feature?

• A. Jaw claudication (jaw pain with chewing)
• B. Chronic coughing
• C. Numbness of the fingers
• D. Left arm weakness

Answer: (A)

Jaw claudication is the hallmark feature here. In temporal arteritis, inflammation narrows the arteries that supply the muscles used for chewing, so those muscles can’t get enough blood during mastication. That mismatch between demand and supply causes pain that is triggered by chewing. This is a classic presentation in an older adult and helps distinguish temporal arteritis from other jaw or facial issues. The other symptoms listed don’t fit this pattern: chronic coughing points to a respiratory issue, numbness of the fingers suggests a peripheral nerve issue, and left arm weakness could indicate a stroke-like event but isn’t the characteristic jaw-pain-with-chewing sign. Recognizing jaw claudication supports urgent evaluation for giant cell arteritis to prevent complications such as vision loss.
