According to the Centers for Disease Control (CDC), you should allow two weeks after getting a flu shot to develop protection against the flu. That's because after vaccination, the body has to work for a while to create the protective antibodies to the flu virus. Bear in mind, though, that there's a lot of variation in how fast different people's immune systems work.
It's been my experience that, unless they hurt like Hell, the shots miss the mark and don't work. They usually take 3 or 4 days to work and don't last long enough. I feel for you-I walked around with bone on bone for a few years-people think that if you can walk, even with a cane, it can't hurt that much.
