Hello Shawna, just like most other skin conditions, this stems from fungal overgrowth and pathogenic imbalance within the body. This imbalance then leads to high levels of toxicity and inflammation as the body shifts from TH1 to th2 dominance (imbalance immune cells). As toxicity and inflammation increases, so does liver toxicity/strain. Your elimination pathways (liver and kidney) are no longer able to push out toxins quickly enough so your body then starts trying to eliminate them via the skin. Toxins sent to the skin triggers tissue destruction as your immune system sees something in your tissues that shouldnt be there. It goes to attack and then ends up damaging tissue in the process. I suggest getting started on a fungal cleanse WHILE doing liver and kidney drainage. You can find the liver and kidney homeopathic drainage protocol under RESOURCES TAB.
I hope this helps and explains a bit more about this condition 🙂 let me know if you have further questions !
