Last Year In June I Ripped My Leg Muscles And

Last year in June I ripped my leg muscles and had to be in the hospital for at least a month because I was dehydrated, I was peeing blood and protein. My liver and my kidneys were affected. Also my ck was so high that the machine wouldn’t even read it. Now in August 2018, I have only been to the gym for a week then stopped for a whole other week. Unfortunately now my kidney hurts a little bit and my ck has risen up a little bit as well. What could have happened to make my ck level rise up again? What can I do to prevent this from happening?
