Toenails grow about 1 mm per month and take 12-18 months to be completely replaced.
good luck!! i hope they grow back

It probably depends why they fell off.

Wear & tear is different to an infection – probably best to check with a doctor.

I lost a fingernail in a sporting accident & it grew back.

the doctor…just to be sure…

however, I injured my big toe while running up and down hills. It was called “black” toe. Your toe bleeds underneath … yours sounds more extreme…

I lost mine and it does take a year or so to completely grow back :-(

What I found out was the toe box in my shoes did not fit me properly … not enough space.

More like you my sister was doing a 3-day 60 mile Koman Walk for a cure and lost 3 of hers that way…she got hers back too..

oh and no neither of us felt any pain…

well just the pain and horror of having toenail less tooties ;-)

kinda messes up the visual affect of the pedicure…

Hope everything is ok, but go see your doctor!
