Diagnosed with PMR and started taking Prednisone in April of 2017. Started at 15 mg and decreased gradually and stopped taking it June 27. On July 6, I started having diarrhea, stomach cramps, chills, nausea and complete loss of appetite. Talked to a triage nurse today who says it sounds like a viral thing and I should start feeling better in a day or two. I cannot remember the last time I had a virus and I'm 81 years old. Could it possibly be Prednisone withdrawal?
