could it be plantar fasciitis? The hallmark of that is a stabbing heel pain that is especially bad with the first few steps out of bed. In the early stages it improves once you are up and walking around.
I hope for your sake that is not it! I have suffered from chronic plantar fasciitis for the last 6+ years and it is very unpleasant.
