What is the house episode that they tell you what is wrong with his leg?

ok so i just recently started watching house and i was wondering what episode do they explain why he limps and what the episode does he almost die??What is the house episode that they tell you what is wrong with his leg?
house explains what happened to his leg in the episode ';three stories';


he almost died in ';no reason'; when he was shot, in ';97 seconds'; when he elctrocutes himself, and in ';house's head.';What is the house episode that they tell you what is wrong with his leg?
I believe the first explanation is in the first episode, where he tells a patient it's from a cardiac infarction, muscle death, etc. Episode is called ';Pilot'; if it matters.His leg is discussed several times throughout the series, but that's the episode where it's first laid out.





He almost dies a couple of times that I know of, once in the series finale of season 2 ';No Reason'; where he gets shot, and in the series finale of season 4, ';House's Head'; and ';Wilson's Heart';, in which he's in a bus crash.
i dont know if this will help at all but there is an episode... idk what season... but he is teaching a class or holding a seminar where he gives three different senarios of sick people. the students gatta figure out whats wrong with each of them. LOL. thats when i found out what was wrong with him....


sorry it was long and full of rambling
His ex-wife shot him . In the episode you find out what happened he is also healed for awhile and he is able to run and everything.


I love that show. I don't know the exact episode.
I think the leg episide was back in the first season, and the other was in the second season.
