Rachel, a 32 year-old woman, who works as a graphic designer, reports gradual onset of pain along the radial side of her wrist, which she initially attributed to overuse while painting and typing.

Swelling and tenderness are noted around the base of her thumb, and she describes a clicking sensation during thumb movement. Past Medical History: No prior history of wrist or hand issues. No significant medical conditions. Medications: Occasionally takes ibuprofen for pain relief, with moderate improvement. Family History: Non-contributory. Physical Examination: Inspection: Swelling over the first dorsal compartment (base of the thumb, radial wrist). Palpation: Tenderness along the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons. Range of Motion: Pain exacerbated with thumb abduction and extension. Special Test: Positive Finkelstein test (sharp pain elicited when the patient makes a fist around the thumb and ulnarly deviates the wrist). What is the first-line treatment for this disorder?( De Quervain tendinopathy?)
