I have a crushed big toe...the right one. A huge boulder rolled out of a wall we were fixing and smashed it.

It turned black, and I lost the nail. It had 2 hairline fractures in the Xray, and I wore a special shoe for a while with it.

The result is that 1/2 of that toe is now numb mostly. But it does not affect my walking that I can tell. Sometimes it prickles, but mostly it is numb. If I flex it in bed it stabs and hurts. Nothing to be done about it...it was crushed. It may grow back, but it has been at least 5 yrs now. Peripheral nerves are supposed to grow back eventually. The severed ones in my surgical left foot did, but it was about 20yrs for that to happen.
Now it hurts occasionally instead of being numb.(instep where you tie your shoes). I can not wear many types of shoes now that hit that spot.

The feet are very slow to heal, if they do. You might try taping that toe to its neighbor, and see if that helps you walk.

You might soak often in epsom salts, as the magnesium may help the nerve heal. But no guarantees. If it starts to hurt all of a sudden, or tingle, that may be a sign the nerves are reconnecting.
