Dear Terry, ;I have a good friend who had the coma treatment with me in Germany, in other words she was there at the same time. She has RSD in the GI or intestines, in her stomach. it is very severe. she has the leg weakness and is in a wheel chair. She has a constant IV via a port for Zofran an anti nausea drug. I will contact her and see if she will post for you. I dont know if she comes here to read or post. But Ill try to find out more info for you. she told me according to her doctors, who are world renowned, RSD in the stomach is not uncommon. Hope this helps Ill try to find out more for you.
