I'm kind of worried , I've been having lower back pain since I started the cleanse (I'm on day 4) and now I have blood in my urine. I've had a kidney stone once before and I kind of think this might be another one . Should I keep doing the fast and just increase my water ??? Can I try eating a whole bunch of watermelon EVEN though I'm fasting? or maybe blend the watermelon with water?? Should I got to the doctor, even though I'm pretty sure this is just a stone? gah, I wanted to go for 30 days, I do NOT want to stop the cleanse just for some stupid stone, but if I need to go get a morophine shot for the pain....I don't know if I'll need to start eating after that or not?geez. maybe it'll only be a small stone.fingers crossed.
