Thanks for your query.Really surprised to know that you are in acute renal failure
and got the appointment for ultrasound
scan after a week.because acute renal failure is a serios in nature and pt has to be admitted in hospital and treated as a emergency.Acute renal failure is a condition in which patient does not pass more than 50 ml of urine in 24 hours and serum Creatinine
level is raised above more than 10 mg%.which gives rise to vomiting Pl co relate do you have these symptoms.If you do not have these symptoms it may be a chronic renal failure
.Pl check your blood for Blood Urea and serum Creatinine levels and consult Nephrologist
to confirm the diagnosis.and further treatment.
