I have/had fasciola buski and fasciola hepatica and perhpas fasciola gigantica.
I had three rounds of triclabendazole that I believe pretty much cleared the fasciola hepatica from my intestinal track, but the fasciola buski is still there and the large fluke (not sure what kind) that is in my tissues is still there. I don't believe fasciola buski can live in the tissues so it much be fasciola gigantica. but it is also possible my perception of their size under my skin is exaggerated and it is simply more fasciola hepatica.
The long and short of it is, I didn't have enough meds to reach out to my tissues or get rid of the large infection I had. I had them for about 12 years.
I've just received some products and I've started treating them again. I did see many die with the triclabendazole.
The Fasciola hepatica and fasciola gigantica can live under your skin. They survive by sucking your blood and dissolving your tissue. They have small but powerful suckers that are quite painful, but I suspect they also put out a numbing agent.
I took triclabendazole last weekend for two days. When I first took it, I could feel a few of their suckers releasing. Sometimes I feel a big pop when it happens. Then they become quite still. You can lose significant blood and those who are very heavily infested actually need blood transfusions. If you are doing this on your own, it is best to plan to stay abed for the weekend and take it easy after that.
Monday I could feel the ones that survived moving back into my liver and the ones in my leg sucking onto my thighs. It was very painful. It is far more painful when they reattach. That is why I suspect they have some sort of numbing agent so you don't feel the pain constantly. I think you mostly feel the pain when they reattach.
So if you take something that makes them release, then you would feel the pain when they reattach. That may be what you are experiencing.
The suckers and blood issues don't relate to most species. AS far as I know it is only some species that suck the blood and can live outside the intestinal track. i'm not sure the other species have suckers at all. You can get a clue by where they are located in your body.
I read somewhere that some 70 different species of flukes can colonize the human intestinal track, but only a handful are pathogenic (cause illness).
I also found that the prazi made me very very sick the first time I took it. I took it for two days only and I was sweaty and feverish. My liver was very bad. But after that initial kill, things got easier. So, after your break you may find that the next time it isn't so bad.
