Why does my pulse feel "stronger" on an area of my body that I recently injured?

By "stronger," I'm trying to convey that it feels much more noticeable.  For example, I broke in some new shoes, yesterday.  This caused a blister on the back of my foot, which burst and exposed the raw skin underneath.  Afterwards, I noticed that sensation that the movie "Elf" described (rather well, actually!):  "My finger has a heartbeat."

Inflammation is a response to injury; and that inflammation is due to increased blood flow to get nutrients and materials to the damaged site. More blood flow is what allows you to feel the stronger pulse.
