question: I saw my Dr on Wed of this week after labs and he told me I have acute renal failure . I am scheduled for an ultra sound on Thur of next week and a follow up visit with my Dr the following Wed to discuss the ultrasound . I am sick and dizzy. I work on my feet all day and can barely function. No initial treatment was discussed. I am scared of walking around and working like this. Is this normal? My numbers were 36 and 1.77
