Calcific tendinosis is characterized by the deposition of calcium hydroxyapatite crystals within the substance of the tendon. We present a case of a 52-year-old female who presented with a 6-month history of right wrist pain, along with a palpable and tender lump in the region of the flexor carpi radialis tendon at the level of the distal radius. Radiographs confirmed the presence of calcific tendinosis of the flexor carpi radialis tendon. The patient was referred for hand therapy sessions and was prescribed nonsteroidal anti-inflammatory drugs, which led to a gradual improvement after 4 months. A repeat radiograph confirmed the resolution of the previous calcific focus at the flexor carpi radialis tendon region. This case highlights the importance of considering rare causes of wrist pain such as this case. Various treatment modalities are available, including surgical management, but ultimately, treatment should be within a multidisciplinary team environment.
