Move your cleats back.
It's a nerve thing. By moving your cleats back, you put less pressure on that nerve. But note that you
might have to make other adjustments to your setup. Pay attention to other twinges of pain on subsequent rides.
BTW - cyclists are not the only ones to experience "hot spots" on their feet. Ladies who wear high heels do too. There's a type of stocking that has a pad at the ball of the foot to help prevent hot spots when wearing high heels. That might help you too.
