Hi Ada,
The advice given above is very sound.
There is one other thing I am reluctant to say to a CRPS sufferer - don't forget that horrible word movement of any kind will help. I am sorry to say this but it is part and parcel of the digestive process & peristalsis. I find it hard too & even harder to say that word "m" word to you cos it isn't easy.

I have trouble walking to the loo, sitting on the loo, getting off the loo, & washing my hands, let alone the rest of it like replacing clothing. I do understand.

It is one of the most difficult things we are asked to do but any movement naturally promotes peristalsis & that coupled with the excellent advice offered above could make a big difference & I would utterly agree with avoiding the chemical laxatives.

Good luck & hopefully "successful" toileting
Auberon
