I'm sorry you are suffering so much with this nasty condition. Hope today is at least a little better for you.

Yes it is perfectly possible for CRPS to affect any internal organ. It is a systemic disease, so it can affect any part of the body. Often problems with organs are not diagnosed as part of the CRPS, as so many doctors don't know much more than the basics about it at best. There is a good Wikipedia page on CRPS that explains it in detail - it is worth printing out and taking to your doctor, and asking him to read it when he has the time.

Good luck, and I hope you get some relief soon.

Bram.
