61-year-old man, transtibial check socket fitting

A 61-year-old man with a right transtibial amputation presents to the prosthetics clinic for his first fitting of a clear check socket on the way to a definitive prosthesis. After walking in the clinic hallway for several minutes, he reports burning pain and a pins-and-needles sensation along the lateral aspect of his residual limb, with the tingling referred into the phantom distribution of his absent foot.
