Thank you for your input. My friends and I haven't posted because we wanted to see other's thoughts before adding our reasoning.
The idea we developed is the character has lost a limb, they constantly feel a slight pain where the limb was, but at times they feel a jolt of pain which requires a save not to suffer some kind of temporary penalty. There's no loss of hitpoints involved, this is long after the limb is gone.
We actually aren't looking to put this in a game. It's just a discussion of the best way the mechanics could handle phantom pain based on whatever rules we can find that already exist, or at least the spirit of the rules where lacking.
Fort saves generally apply when external forces act upon the character: heat, cold, overexertion, poison, etc. Whereas will saves take effect on anything affecting the mind or soul.
I reason it's a will save. Phantom pain is entirely in the mind, when the mind tries to interact with the missing limb it mistakenly interprets the lack of sensation as pain. The limb, or lack of limb that is, sends no signal to the mind and therefore shouldn't be a fort save. One could even argue the pain is an issue of the soul which is trying to interact through body no longer there.
Personally I'm playing around with the idea that phantom pain could be ruled as an extraordinary curse of illusory pain. The idea of a non-magical illusion is weird but the actual pain of phantom pain is truly illusory in nature; even it's name "Phantom Pain" is derivative (at least etymologically) on the idea of a Phantasm.
Although this phantasm isn't magical or visible it is mental and perceived only by the subject, totally in the mind. It is a personalized mental impression, all in their heads. Additionally, of the varying illusion types, phantasms (along with figments) remain even after a character successfully disbelieves the illusion.
Here's some quotes from the SRD for easy reference:
Illusion spells deceive the senses or minds of others. They cause people to see things that are not there, not see things that are there, hear phantom noises, or remember things that never happened.
Phantasm: a phantasm spell creates a mental image that usually only the caster and the subject (or subjects) of the spell can perceive. This impression is totally in the minds of the subjects. It is a personalized mental impression, all in their heads and not a fake picture or something that they actually see. Third parties viewing or studying the scene don't notice the phantasm. All phantasms are mind-affecting spells.
A successful saving throw against an illusion reveals it to be false, but a figment or phantasm remains as a translucent outline.
