I get these exact symptoms when I do a water fast. I have been trying to find someone with the same thing as me. What day did the pains start? Mine starts in my legs and then it moves to my thighs etc and by day 4 I can't even stretch my muscles and it feels like all my ligaments are tight. The muscles aches are extremely painful. As soon as I eat the pains slowly go away and after a few days I am back to normal. I have had legs pains for most of my life. Let me know on what day of your fast your leg pains start.

I had some leg pains at the beginning of the MC. I have also suffered from major leg pain in my calves espescially when it was cold. I figure it must have been toxic uric acid build-up (gout), because my pains lessened considerably (about85%)after finishing the last MC. I can now go outside in the cold evening without worrying about the horrific pains I used to have. I also had stiffness in the joints in the morning and now they are gone. I guess these and many other health benefits are reasons besides weight loss to do this awesome cleanse!
