Yes I did, I was actually in the hospital with renal failure and developed Rabdomyalsis which is a breakdown of muscle, got dehydrated because the meds I was taking for my RA made me nauseated and gave me diarrhea all this elevated my CK, once my kidneys started working against n my !eve! Went down. Are you hurting, I was in terrible pain?

Please look up Fatty Acid Oxidation Disorder. it causes high levels of creatine. I have been told that L-Carnitine and going on a fat free diet helps with this disorder.

Thank you for this suggestion!

I hurt chronically but worse during a flare up. My flare has since calmed down. I just thought the ck level increase during a flare was interesting
