I had kidney pain a few months before I did my 60 day fast. On day 18 of the fast I passed a small calcification--owee!! Luckily I was fasting with the supervision of my excellent naturopath, who was able to prescribe homeopathic and herbal support and I fasted through--- but the crisis lasted a week!
The good news: Since then I have had NO problems with my kidneys!
KEEP DRINKING! The parsley, or Celery seed, or Watermelon seed teas are highly recommended for kidneys.
Glad the pain is decreasing! FLUSH FLUSH FLUSH!!!!
Since I have done considerable cleansing, I no longer have any joint aches, as I used to. I hope cleansing will help ease some of your discomfort.
