The most common issue for posters here because their spouses have CRPS and they want to be supportive is dealing with the feelings of powelessness because they can't "fix" the pain for their suffering spouses. I really like Adalaide's suggestion to do some of the little things, even if your wife could them herself, just to show her that you are there for her.

I give you kudos for reading up on CRPS and finding this forum. I have one of those spouses who doesn't understand CRPS and who doesn't care to learn. If you you feel that you weren't there for her a much as you should have been, I hope that you are able to show her now that you are fully committed to support her in her struggles with chronic pain.
