I recently had a colonoscopy and an ultrasound. The colon had microscopic ulceration and the ultrasound showed multiple cysts on the liver. (Flukes leave cysts.) The doc said he didn't know what caused the cysts when I asked him, but I also told him I predicted it. I have had liver and abdominal pain for months. Every O&P has come back negative. When I send the labs an actual specimen and leave instructions for the specimen, they throw it out. It's not part of their protocol.
