If IVM makes them stop, think ... the worm is round.
If Praziquantel makes them stop, think ... the worm is tape or oval fluke.
If you dose Albendazole and they wip back and forth in the sinus, in a day or two, think round.
Round favors sinus, skull, eyes, lymph, ears.
Tiny round babies favors the right side of the body, since the heart and lung filter them out. I could see the round migrans in my right hand when I first started to dose Albendazole. Look close, they look like say 20 thousandths wide, and go for say 150 thousandths long, and show for a couple of hours, little red streaks.
If you get sores on your right shoulder, think babies of blood parasite (round or oval).
I have made a lot of generalizations here, to simplify and make a point.
