Well, the mebendazole was not a cure. I've begun to feel movement under my skin again. It could be filial worms, I suppose.
My ear is better, but there is a thin red line that extends down the perimeter of my ear. When I apply heat (such as heating pad), there's a squirming sensation.
I will try the Demonex shampoo for sure.
I'm also going to try Abendazole. It's one of the few anti-parasitic meds that I haven't tried yet, so might as well give it a go.
