Just two quick questions:

Does the Cruciatus Curse actually cause physical pain or is it all in a person's head?

Have any other forms of torture been mentioned in the books? If so, what are they? And if not...could there be any different spell, perhaps with resulting in a different kind of pain?

I kinda forgot how the Cruciatus Curse's pain is described and I don't have my GoB with me. Anyone?
