My kidney function has been elevated for awhile now, Creatine is the main one, from what I have read previously it is just a normal side effect of ME/CFS which I have told my Dr. as I didn't think there was much to be done for it. My labs from last Wed. came in today and they want me to do a kidney ultrasound now, but I just highly doubt that will be of any benefit from what I have read. Are there any other more specific tests to do before doing that? and would it help to get the ultrasound? Any thoughts? Thanks in advance, it is nasty weather here, so that effects me so bad as well.
