Hello, I started the hcg diet about a week ago 500 cal/day. About 5 days into it developed a sore throat, day 7 extreme total body muscle pain that are constant accompanied with a low grade fever. . Stopped the diet at day 7 concerned that the hcg had slomething to do with it. I ve done no exercise or strenuous activities, no trauma @ day 9 still left with muscle pain mostly moderate occasionally mild, mild sore throat and extreme weakness. Any ideas?
