Does anyone have suggestions for a parasite cleanse for me?

Hi all! I hope everyone is having a relaxing Fourth! I have been very ill for many years. I know I have candida but I suspect parasites as well. I had twenty colonics done this past fall and winter and after many of the sessions ( after I got home ) I passed some white tissue looking things with a red line through the middle. Here is my dilemma. I also have lots of pain and inflamation in my lower decending colon. I think it is from many years of chronic constipation?? It burns often after I take many herbal things. Sometimes even foods makes it burn. I tried Paragone this past winter but in just a few days was in a VERY bad way with the intestinal pain/burning so had to stop the cleanse. Does anyone have any ideas for things to kill the critters? I keep treating my candida but I never seem to get well and my leaky gut and colon inflammation is getting much worse! Also does anyone have any idea why I am having all the pain and burning? Thank you in advance for your help ~:)
