Which history of present illness (HPI) question SHOULD be asked if thoracic outlet syndrome (TOS) is suspected?

In thoracic outlet syndrome, symptoms come from compression of the brachial plexus and/or the subclavian vessels as the shoulder and arm move into certain positions. The most informative HPI question is whether reaching the arm overhead makes symptoms worse. Elevating the arm narrows the thoracic outlet space where nerves and vessels pass, so neurogenic or vascular symptoms (numbness, tingling, fatigue, weakness, or color/temperature changes in the hand and arm) are often provoked by this posture. If patients report that overhead reaching worsens their arm symptoms, it strongly supports TOS and guides further examination with position-specific provocative tests. Asking about occupation or daily tasks like dressing is less specific because many conditions can affect function, and they don’t directly reveal positional provocation of symptoms. Asking about coughing, sneezing, or straining can be relevant to other conditions that affect intrathoracic pressures or nerve/vessel compression more broadly, but it’s not the classic, most informative prompt for identifying TOS.
