What type of food should i eat when my cpk has been elevated due to muscle injury in my calves?

Lots of fluid: In additional to keeping your urine very dilute it is important to keep the urine alkaline as well. This helps your kidneys to clear out the protein breakdown of the muscle injury. It's best to work with a doctor to do this well, but in general eat more alkaline foods like vegetables and even consider taking small amounts of baking soda.
