Will I ever be able to walk again?

I think it's pretty safe to say you will walk again when your toe is healed.

You could have a hairline fracture how swollen is it?

You may need to go to a doctor?

I suggest if you need to put weight on it before the swelling goes down if only so you can limp to the pharmacy or doctor so do this

wrap some cotton wool around the swollen toe lightly not tight and put cotton wool under that toe and the toes on either side put a bandaid or surgical tape if you have it to secure that or wrap a long roll type bandage over that

now you should be able to pull a sock on and put on a loose sandal or th or something

limp down to the doctor if you can now put some weight on it or get some one to drive you

or go to pharmacy and buy some foam padding

whatever you did to it the swelling should go down eventually

finally if the swelling lasts more than a day or two and there's lingering discoloration or the swelling spreads to other parts of yr foot see a doctor or emergency room asap

Does your toe hurt or did you sever your spinal cord? It's pretty easy to figure out.
