Kidney Failure :: Creatinine Shoot Up In 3 Week Times?

3 weeks ago, i was admitted in hospital. over my 2 weeks staying in hospital, doctor didn't do anything, didn't on drip . just give me injection of Hydroxychloroquine.and i was diagnosed with urine infection. so creatinine able to goes up from 160-210. but down again to 155.

however, last few days, my creatinine shoot up to 240. such a shocked to me. as i didn expect there is so much shoot in just few weeks time.

doctor has been stop my enalapril, which i used to protect kidney and keep my urine protein negative.

however, there is 1+ urine protein in my urine test. my blood pressure used to below 130/80. now sometime, it can shoot up to 150/95 if i do some physical activity.

i have been worried for my condition. This year, i was admitted twice. Jan admitted due to diarrhea and dehydration. delay the admission. so creatinine shoot up to 400++, nearly need dialysis. however, after drip. then able to drop to 150++

then during march usual check up. my creatinine also shoot up to 240. however, after the hospital stay, it manage to down back to 150++

i wonder is it because i started to work and sometime i worked quite late. then my creatinine shoot up so much?
