Shaving bumps??

I've noticed that along my jawline and up the side of my face, there are little red bumps. Is this a side-effect of shaving, and my skin is just too sensitive, or what?

I'm using a sensitive skin shaving foam by Edge, and a Venus razor. I've tried a Gillette razor, and just a simple disposable razor, but they gave me the same result.

And products or quick fixes that I could use to reduce these red bumps? The rest of my face is pretty much clear.
