Creatinine Test Results

[Luckee123]

I had a problem with muscles seizing up and had some blood tests done by the ER who told me to take them to my dr for further evaluation.  They stabilized me with a muscle relaxer and Ativan at the ER and said that they could do nothing further in the ER setting. The tests were normal except for these two, which were slightly low, and I'm wondering what it could mean in light of the muscles seizing up like that. They are:

BUN:  9
CK:  54

Appreciate any help.

Isn't BUN the measure of urea in the blood?

I am female.  They didn't do a urea count that I see. I take ibuprofen and some tylenol for neck inflammation and pain and don't workout.

if your creatinine is low, then I would suspect that your diet is weak, but you don't say if you are male or female (which makes a difference)  sounds like a kidney problem, except that these levels are usually elevated if you have poor kidney clearance - also your urea count would be higher but you don't say if you had a urea count done.  Do you take any drugs and if you do which ones - they can impact kidney function. In the clinic where I worked, muscle seizures were caused by too little hydration in the blood system - do you drink enough fluid during your workouts?
