Anybody ever get ulnar nerve entrapment? That's where your pinky gets numb and you can feel tingling up to your elbow, like when you hit your funny bone. I just started playing a lot in the last 6 months and now I have that, it's definitely from pinball. Not sure if it's due to repetitive stress, or an awkward, too late attempt to nudge on a ball that flew off the slingshot into the outlane. It's not serious, but it could be if it gets worse.
