Gregory Houses limp?
He had an infarction (where the leg is getting inadequate blood flow) in his leg. It was left undiagonsed for 3 days and caused the thigh muscle to die. Instead of getting it amputated he wanted to do a bypass procedure to still use his leg. They put him in a coma and his girlfriend at the time Stacy went against his orders and the doctors just removed the dead tissue. Because she did this he has lost partial use of his leg and is in constant pain that’s why he limps and pops pills.
