Before my hysterectomy, or rather my liberation from the feminine product isle, I sometimes would have pain while I was walking on my right side. It was a fibroid near my ovary. I've read that the Master-Cleanse can clear up fibroids and cysts so maybe it's inflamed from all the detox and maybe it will go away. I first noticed a pain while doing yoga (the lunge pose) and it definitely hurt more when I was ovulating. Just my two cents. I wouldn't give up on the Master-Cleanse yet. Some people have intense detox symptoms...
