I just wanted to leave a couple of sites regarding central pain syndrome - post stroke pain, that Aussie mentioned above (sorry your father went through this too, Aussie).

NINDS Central Pain Syndrome
Also wanted to let you know there is a
Stroke Forum here at NeuroTalk. It is a very quiet forum, but you may find information in the older posts by using the Search feature.
