Kidney Values Lowered

Crystal has had kidney issues for 7 years.  We have been able to keep her Creatinine down to 2.1 (below 2.0 is "normal") with herbs, bicom and color therapy (Crystal loves the Scarlet and Magenta lights). She does not follow any special diet and can not receive fluids because of heart issues.  In October, Crystal's Creatinine went up to 2.7.  What had changed?  During our busy Fall, I had let our color therapy sessions lapse.  I went back to treating her 4 or more times weekly.  I also was able to get an occasional acupressure session in (Crystal only allows this in "special instances"...she absolutely decides when).   Last week at recheck her Creatinine was 2.1 once again.
