44-year-old male presented with complaints of discomfort along the posterior aspect of his distal right lower extremity. It began acutely after feeling a popping sensation when running about 1 year ago. He experienced an initial burning pain that gradually became a numb discomfort extending to his lateral right ankle. His symptoms were recalcitrant to the use of foot orthoses, application of heat and ice, over-the-counter topical analgesics, and consistent heel cord/calf stretching. He was most concerned as he has recently appreciated a focal area of swelling that coincides with his area of maximal discomfort.
His past medical history is remarkable for hypertension, stage II chronic kidney disease, and possible congenital polycystic kidney disease.
