Hi, I have similar problems. I'm suffering from flatworms for almost 5 years since I came back from Spain where I ate some bad meat (raw burger or something).
I had Tapeworm but seems that I got rid off it after I ate tons of garlic. But I still had symptoms of worms:
3. itchy anus;
5. pain in stomach and pancreas.
For this period I took lots of various medicaments I could find in Russia:
mebendazole, albendazol, vermit, pirantel, praziquantel.
But they have no effect. I'm taking Biltricide (Praziquantel) almost every day. That drug reduced diarrhea and made me feel a bit better, but I still have flatulence, itchy anus and pain in pancreas.
I'm sure I have flukes because I saw 1 big fluke which came out after I've been taking Biltricide for 1 week.
I even ordered Artemisinin from Germany but it didn't have effect.
Niclosamide (Yomesan) isn't legalised in Russia so I'm planning to order it from Germany (it will be very expensive).
Yomesan will be my last hope because I feel really bad.
I was diagnosed with pancreatitis and gastritis but they didn't find any worm eggs/antibodies in my feces/blood.
I'm so upset, I spent so much money on doctors, analysis and medicaments. Yet nothing helps me :c
