Sorry girls, I bet this is the dumbest question ever....

Have you been tested for coeliac disease? It's quite common to have it when you have CRPS, it's another auto-immune disease...

The diarrhoea, weight loss, stomach cramps etc all sound very familiar. I felt so poorly before diagnosis, it affected everything, and i felt a lot better on a guten-free diet - once my doc had finally agreed to send me to a gastroenterologist (took nearly two years to persuade him, omg). If you really don't want to do tests, you can just try going gluten free and see if it helps, but you do need to be very strict, I'm sensitive and even the tiniest amount makes me ill.

Just a thought. Sorry if you already have it or have been tested!

Bram.
