Is there any harm in starting this program if you have swollen lymph nodes in your neck? Mine have been swollen on the right side for about a year. Will it hinder my detoxing?

You should be fine on the program. As the first two weeks are meant to build, boost, and cut inflammation in the body, you should feel much better after that. If not, you can take the pathogen purge slowly, starting out with half the dose. Here in CA, we have something you can do before your colonics to flush the lymph system, called electromagnetic lymph detox, where they flush your lymph system (it dumps back behind the heart). Then when you have your colonic, you release a ton of toxic lymph fluid. Please research this and see if it's a possibility for you or look into a lymphatic drainage massage. Also, drink warm water daily for a week (little sips of it, no lemon, no tea, just warm/hot water). This will dilate and hydrate your cells and flush the lymph system. Infrared saunas are also helpful for congested lymph.
