Tom, a 43-year-old architect of Caucasian descent, presents with a six-month history of polyarthralgia and tiredness, which is impacting his ability to run his company.

Recently, Tom has experienced dull aches in his joints, especially in his right hand, wrist and elbow, with associated stiffness in the morning, which gets better during the day after some movement.
