My sister dunked hers in metho and her partner set it alight. It was just mucking around, he’s an idiot, but it fixed the infection

I thought this was an interesting question because a couple of weeks ago I thought my big toe nails looked like they had a fungal infection but it seems to have gone. I’ll keep an eye on the situation and if it flares up again I’ll talk to my Pharmacist.

Vicks stops it

Your pharmacist should be able to give you excellent advise about the best product to use.
There is a product you can paint your nails with the same as you would nail polish. You may need to consult a podiatrist if it is really severe if it is your toenails. They do some medical studies to know the causes. My Mum had some when she was about 85 y.o. She was told not to use nail polish so her nails breathed. (she didn’t use nail polish so that wasn’t a solution for her)

Maybe advice from GP or chemist?
