This would have certainly been simpler for me had a single flush ended my symptoms, but it didn't ... it helped enough each time to keep my flushing.
As for what do flukes look like...
I saw what looked like tiny glass straws that were tomato red, then there were what looked like undigested tomato skins. Since I'd eaten NO tomatoes, I asked here and was told it was part of liver flukes. Then I've passed heaps of red flukes, I braved to see what they feel like ... best thing I can say is the consistantcy is like that of a rubber fishing worm ... apprx 1/2" long.
