I wonder why I might be having itching all over my body, more at some times than others. I have had lichen sclerosis for many years and Sjogren s Syndrome. I also have severe chronic diarrhea, for which I am being investigated, starting to see a GI. I think I may have some pancreatic dysfunction because I have had diarrhea for a long time. I also have had anal cancer, treated with surgery, chemo, radiation. The diarrhea used to be called lactose intolerance, then IBS, then radiation proctocolitis. I have tried many dietary limitatons.
