Ah Geez. I feel your pain. Take it from an "expert" tingly fingers/hand can indicate bruised nerves. If it continues, please go to the doc. Remember, anytime you fall at work, report it. If you ever, ever have to go on Workman's comp, it's on record. It doesn't mean you're "mad" at your bosses, you're entitled. It's taken out of your paycheck. Feel better. Hope you iced it
