<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, my creatinine, serum level is 1.33, what does this mean? I have coke colored urine, low grade fever, and terrible headache that wont go away. Also my eyesight of 2015 checked last year has gone down considerably. When I went in to get my license renewed, I was told I am considered legally blind in one eye. Please help me figure out what is wrong. I know I have to go to a specialist but no one has an appointment for weeks and I dont wont to stay in the dark that long. Thanks  <response>: Hi dear, welcome to Chat Doctor. Kindly see your physician straight away urgently. You need to check your BP, have certain blood tests CBC, KT, LFT, Clotting, etc., scan of the kidney ultrasound at the very least. The doctor will have a look at the back of your eyes retina as well. Creatinine of 1.33 is mildly abnormal only but once again it depends on your age, sex, race and BMI too. CONSULT A Doctor PRONTO!!!
