About ten years before the series began, House entered into a relationship with Stacy Warner (Sela Ward), a constitutional lawyer. Five years later, during a game of golf, he suffered an infarction in his right leg, which went misdiagnosed for three days due to doctors' concerns that he was exhibiting drug seeking behavior (House eventually diagnosed the infarction himself). An aneurysm in his thigh had clotted, leading to an infarction and causing his quadriceps muscles to become necrotic. House had the dead muscle bypassed in order to restore circulation to the remainder of his leg, risking organ failure and cardiac arrest. He was willing to endure excruciating post operative pain to retain the use of his leg. After House was put into a chemically-induced coma to sleep through the worst of the pain, Stacy, House's medical proxy, acted against his wishes and authorized a safer surgical middle-ground procedure between amputation and a bypass by removing just the dead muscle. This resulted in the partial loss of use in his leg, and left House with a lesser, but still serious, level of pain for the rest of his life. House could not forgive Stacy for making the decision, so he left her. House now suffers chronic pain in his leg, and has to use a cane to aid his walking.
got in a motorcycle accident.
i dont know the exact term but the muscle in his upper leg died.

He had a blood clot in his leg that led to muscle death. He was in too much pain so they put him in a chemically-induced coma. His girlfriend, Stacy, was his medical proxy (made his medical decisions for him while he was in the coma) and had the doctors cut part of the muscle out of his leg. Now, he walks with a cane and is in pain all of the time. He is addicted to painkillers because they help ease the pain and he cannot function without them.
