Hello! If you feel them... It's most likely roundworms (esp ascaris/very common). I see that you didn't tried albendazole? Try it using ICU protocol. And yes they are in my head as well now and crawling all over my body. Scary indeed. But you not alone... Don't panic... I also don't think that they can penetrate brain (they are usually in the dura area layer). My stools were negative as well (rubbish and unreliable). To be sure you have this specific parasite
do a blood test to see if you have elevated white blood cells called 'eosinophils' (they hunt large parasites) if they are 30 or over you most likely fighting Ascaris
lumbricoides. I have over 30. This parasite
cause eosinophilia. And while eosinophils can be elevated for many reasons.... Eosinophils mainly elevated during severe allergic reactions and parasites
only. This 2 things are closely linked anyway. Also changes that you are infected with Ascaris
are higher as well than any other parasite
esp when you feel the crawling, twitching, etc.
