I have always had itchy skin on my back past 26 years. I have back scratchers in every room of the house. In the past couple months, itching has become worse, interrupting my sleep or preventing sleep. I am just recovering from an intestinal flu, with diarrrhea and vomiting. I have a permanent ileostomy which can cause rapid dehydration, and was experiencing symptoms of that, which I am very familiar with, so went to the ER, was given a liter of fluids. All blood work came back negative for bacterial infection and C-Diff. I was told I had a viral infection. Ok. Makes sense. Was told to increase my probiotic supp. to twice daily. The itching may be a result of dehydration, but it seems so intense past two days, especially at night. Liver involvement?
