Q. A 30-year-old patient presents to the clinic for her left wrist pain that has been worsening over several weeks. She reports that the pain is severe when gripping objects or twisting the wrist. Her vitals are normal. During the examination, palpating the first dorsal compartment near the radial styloid shows tenderness. The patient's pain significantly intensifies when asked to perform a specific maneuver, making a fist with the thumb enclosed within the fingers followed by ulnar deviation of the wrist. What is the most likely diagnosis based on her clinical symptoms and examination findings?
