They are very common in horses, I never realized humans could get them. The moxi worked for me when I had scattering and it killed everything thing that scattered in two days. Yes it knocked me out for a whole 24 hours but was worth it. It can induce coma so be caustious but when nothing else works in animals vets use this. Maybe you can kill the bastards with monthly doses to knock them out and the fen ben combo. I wonder how these are caught. I think many worms are crossing over to humans. I'm glad it is helping you.
