My daugher is 18 and has CFS. She has a history of candida, but we have that under control. Her doctor wants to treat her with oral DMSA to chelate metals. My daughter is very sensitive to supplements and meds. Will DMSA (being a sulpher compound) cause candida to come back? Also, I've read that EDTA suppositories are more effective than oral DMSA. Does anyone know if EDTA suppositories are safe for sensitive CFS people? Thanks!
