Sed Rate Blood Test

I recently had rhabdomyolysis and my kidneys have stopped working. Fortunately over the last three weeks, I went through many steps to get healthy. I had my blood test results back today and the nurse said that my creatinine (was 6.4) and CPK (was 25000) are back to normal my blood Sed is a little high. What exactly could or slightly elevated sed rate means in terms of my body?

It is a very non-specific inflammation in the body. It does not point to anything specific.
