Tony,
First of all, I am so sorry you are suffering like this. Having dealt with bowel issues for many years due to Irritable Bowel Syndrome and now more recently with the Pelvic Floor Dysfunction, I can relate to you and understand your pain.

Just knowing you have the IBS, I am wondering if you have been properly tested for Gluten Sensitivity? Have you gone over the gluten file here? Gluten sensitivity can cause neuropathy in some people.

A lot of people suffer with this problem and don't know it.
