I can't move my toes after having a nerve block put in place for ankle surgery - is this normal?

I would wait : It out and see after a few hours when the medicine wears off. It can be completely normal.

Yes, it is normal: Feeling and motor control will return anywhere from 4-24 hrs, depending on what type of anesthetic was utilized for the popliteal block. No need to worry.

Yes: But it shouldn't last more than 8 hours. If it does please call the doctor that placed the block.
