Good luck. I have a pretty good idea of what you are going through. My wife had kidney failure as a result of a reaction from a colesterol lowering drug. She was the one in a million as they state on the warnings. Her creatinin went up to 10 in the emergency room. After about 6 months of dialysis she became well and everything is back to normal. That was a couple of years ago. So far she is fine.
Listen to the Docs do what they tell you and you will be fine too. It just takes time.
