Serious Q for all bloodwork pros

[MANWHORE]

Only thing wrong is CPK is high .. 1st was 800 with 300 being top normal and doc took blood week later and was high 7s .. he wants me back in soon for more tests so tell me what can i do to lower it .. he says kidneys are fine but high CPK can damage them or stress them .. IS this true or is this just someone talking about something they heard like high protein being causing stress to kidneys when really only stesses when there is a preexisting problem ... I know multiple IM injects will raise CPK but do you think that high .. I probably do about 6 injects per week but i use anywhere from 5/8 to 1/2" 27g pins .. Not much tissue damage there i'd say ... Was thinking something else to ask but i forget right now . .too tired .. I sleep about 5hrs/night .. 30min workouts mostly deads,squats and incline bench but don't really kill myself in there .. I do have to drink more water which i have been doing and get more sleep which is hard because most of the time i have alot of energy at night .. I figured since i am pushing/pulling weight i naturally couldn't do that these heavy (4-5 reps and i'd say pretty intense last reps) compound movements are damaging my muscle tissue alot more than would be if i was off cycle and may be the cause of higher CPK levels .. not familiar with CPK as i never heard of it before so someone please fill me in .. thank you

CPK stands for (I think) creatinine phosphate kinease.

It's a measurement of how much of your muscle cells insides are on the outside. Basically it's an indicator of how broken down your muscle cells are. When stressed (due to a variety of things to include lack of sleep, exercising etc) the muscle cell walls break down and leak their insides into the blood stream. This is indicated by a high CPK. It could be a bad thing or it could be normal due to your workouts.

As for it affecting your kidneys, never heard of that but I can't say one way or another.
