The colon cleansing products might help. I would be looking for a practitioner who is EXPERT in abdominal massage, yogic abdominal massage would be good. I know this may seem like the last thing to want right now, but if you are experiencing some ICvalve pain as well, it points to a problem with the entire digestive system not just the GB/liver area, and as you continue to cleanse, kill parasites and get better, the right kind of massage can really really help you get over the bumpy patches!!
Another thing, if you have IC valve pain I would recommend you don't do colonic irrigation (it is too harsh on the ICV), but instead have enemas and or colemas, if you can.
Galaxony has a great vid on how to make suppositories too.... if you don't already know about this check out her posts.
