Just talked to a buddy of mine at work, and he informed me that he has to go in for surgery because of high levels of creatine in his kidneys.
He said that one morning he noticed blood in his urine, so when his doctor did test, he found a high level of creatine in his kidneys. So, now they have to go in to see what's causing this.
The guy hasn't used creatine in years, so it's not that. Anybody heard of this, cause I'm thinking of not using it anymore?
