Creatinine and Myglobin

Good day. Anyone here have extremely stiff and chronic 24/7 muscle pain, cramping, etc? I'm pretty sure that is what is driving my creatinine levels to absurd levels, not exercise or working out- which I often avoid doing a week prior to the test. My massage therapist and physio are saying I'm one of the most stiff patients they have ever seen and often don't know where to begin. My personal opinion this is a leaky gut and subsequent yeast issue, but I've never seeemed to have fully cleared the yeast and the gut has never healed. Anyway, any thoughts on this constant state of stiffness and cramps in my muscles would be the creatinine elevation cause and the signs of muscle wasting via the myoglobin?
