Had the same problem because we stay in bed a lot soak it in salt water and try not to where socks and keep your toe nails short and like I said soak your feet in warm salt water after a few weeks it should be better all my best to you

Makes sense since some of our DMTs are fungicides. My mom had an issue with that - she said Vick's Vapor Rub (& socks at night to keep feet moisturized with it) took care of it in less than a month.

Fungus is certainly more common in MS. I fight it too. I have a non-prescription liquid that I paint on my toenails every day. Looks like it’s growing out. I got it from having pedicures, which I used to get at least after I was no longer able to do them myself. I stopped getting pedicures & it seems to be clearing up.

My husband does a Vicks vapor rub on his toes for nail fungus

Tea tree oil clears up all kinds of infections. And if that doesn't work, apple cider vinegar.
