Limping Along

Y'know the worst part about having an ailment that sounds silly even though it really isn't? Having to explain to your boss why you're not fit to work. Especially when your boss doesn't take time off for any injury/illness (even though he should,) and your coworker has been working full-speed with a cracked rib for the last few weeks. I'm not going to risk my foot not healing properly for the sake of impressing a boss, but I wish there were a less feeble-sounding way of saying I've got a sprained toe.
