I never experienced these recurrent fungal infections before

I never experienced these recurrent fungal infections before. Got a fungal infection on my big toe on the right leg last year and I didn't even know that was a fungal infection. Left it like that for 2 months and it got worse. I ended up removing that toe nail and it's still growing. It's been 7 months since the removal and 70 percent of the nail is grown. I have been told to use ketocanazole ointment everyday until the nail is fully grown. I am dealing with other healing issues as well.
