The pig bladder just might work. My friend has had over 80 surgeries to hold his guts in after getting his arm ripped off and his guts ripped out. After all else failed they did it with pig guts. I saw a picture of him on my facebook today and he looks good. I think it might be working for him so I am thinking it might help you. Let's hope anyway.
As far as amputation, the symptoms are still there. I don't think that is the answer. I know you hope it would be but I doubt it.
Keep trying new things. Hopefully there will be an improvement as time goes on.
The weather has changed here and my RSD is doing it's thing and boy is it hard to keep my mind off of it and how to get it to calm down.
There is no easy answer. I was doing ok all summer except for my CFS from the heat and now I am in a total flare.
Glad you found this group. You will get some new ideals from here.
