My age 51, I am getting foot irritation (might be water in feet) initially my anal part is some kind of itching and my urinary track infection. My health condition is diabetic (a1c - 7.3) started taking medication (metformin per day). One feet is clearly feeling like some kind of tingling sensation which is rotating in middle part of feet. I am assuming bladder problem, I request you please suggest me exactly what type of scan or test I need to take for clarification weather it was due to diabetic or urinary bladder issue or fatty liver issue.
