Since a bout of cancer in 2004, I have had fungus in my big toe nails.

They were never able to treat because I have no thyroid now, and take large doses of synthroid to compensate.

At the beginning of july, I rubbed some of my horses Invamectin on my toes.

It seems to have cleared...

For many years, I have had flare ups of athletes foot (only my left foot).

Towards the end July I rubbed Invamectin on the whole of my foot

It seems to have cleared it too, although it will take longer for me to confirm that, as the flare-ups are not regular.

Are the 'fungus' really parasites? Is the 'fungus' a side effect of parasites?

I do not know, but, so far, an anti parasitical cream, seems to be working....
