My dad has nasty fungus lookin toenails and i think i got it too, my toenails are extremely brittle and crumble when i trim them, other times, i can just peel off the nail with little to no pain, what do i do to treat this and stop it?

There are effective treatments for fungal toenails but they require a prescription. You will need to see a doctor and a foot doctor can definitely evaluate and treat your toenails. So, see a foot doctor to have your toenails treated. Good luck!

Fungal nails are difficult to resolve. You seem to have inherited your dad’s immune system with the inability to fight off fungal infection to the nails. Oral antifungus medication. Topical will not resolve this problem but can help overall Lamisil cream is a good nonprescription antifungal Liver function studies required prior to taking meds
