I was diagnose with SOD few years ago. I have not had the test to confirm the diagnosis because I did not want to have it due to the risks involved. I had SOD symptoms before having my gallbladder removed. I thought the the pains and digestive problems were related to the gallstones but a short time after the operation the pain and problems came back. Is this possible that I have been suffering from SOD for a long time? or could it be something else?
