Well, the best I can tell you is you are having severe die-off. Do you have any pre-existing conditions besides the bad leg? I had a few days of achy, tired, flu like symptoms when I first started, but I didn't have much more then severe fatigue and low blood Sugar before that. Are you drinking enough water? You are Zapping a lot, so it would be good if you could take some probiotics, eat yogart or Kombucha to help replenish any good bacteria you might be losing. Do you have any MSM? It really helps with aches, and it helps toxins loosen and get out.
