My CK has climbed up over 1000. (It was 8,900 in 2005) and then went down to 156 over the years. Now it has started to go up again. So far - no kidney or liver problems. Cardiologist suggested that elevating CK could be due to gemfibrozil. I stopped taking lipitor in 2005 when I got weak and muscle pain. Biopsy showed "dead and dying muscle cells" not inflamed noes.
