Which history feature is commonly elicited in patients with suspected thoracic outlet syndrome?

Overhead arm use is a classic trigger for thoracic outlet syndrome because the space through which the brachial plexus and subclavian vessels pass narrows when the arm is raised. This dynamic compression during repetitive or sustained overhead activity leads to symptoms like numbness, tingling, or weakness in the hand and forearm, often worse with the arm elevated and improved when lowered. The other history items don’t fit: a visual aura points to ocular or cerebral phenomena, leg swelling suggests venous issues in the legs, and a recent lower respiratory infection relates to lung or airway problems rather than the shoulder girdle outlet.
