W: Well, Mr. Jason. There is a nerve running behind your knee and your hip and through your spine.
M: Ehr.
W: When you lift your leg, that nerve should fly in and out of your spine quite freely. But with your leg, the nerve won’ t fly very far. When you lift it, the nerve is trapped and it’ s very sour.
M: Ay!
W: Now, what’s trapping the nerve? Well, your MRI scan confirms that you got a damaged disc in the lower part of your back.
M: Oh, I see.
W: The disc is a little pat of gristle which lies between the bones in your spine. Now, if you lift heavily in a wrong way, you can damage it. And that is what happened to you.
