I bet it still hurt, though. Apart from static shocks which are very high voltage but very small current, all my shocks have been mains ones
- due to my own embarrassing stupidity.
In the first case, as a teenager, I was working on a mains-powered reel-to-reel tape recorder. I turned the power off at the appliance switch so everything was safe... except the "input" live pin of the switch :-( I happened to touch the knuckle of one of my fingers against the live and neutral terminals that were connected to the mains lead. Hurt like hell for ages after, maybe because when only a few millimetres of skin are involved, there's lower skin resistance so higher current. My knuckle had two marks on it like fang marks of a snake bite. It didn't help that the shock made me jerk my hand away and I gashed it on something sharp.
The second case was only a couple of years ago, and it's a cautionary tale about Philips Hue bulbs and other similar ones which can be turned off internally by an app even though there is power to the terminals. I'd been gradually changing the GU10 light fittings in the grid on the bedroom ceiling, which involved removing each old fitting, pulling down the junction box, un-wiring one fitting and wiring another in its place. I'd been scrupulous about turning off both the wall switch and the circuit breaker at the "fuse box". Later on, my wife said "Can you just do those ones as well?" All the bulbs were off so I thought "the wall switch is off - it's safe". Wrong! The fittings were live but all the bulbs, controlled as a single "room" on the Hue app, were turned off. As I discovered... That shock was painful but nowhere as near as bad, probably because the house RCD tripped within the stated 30 msec, faster I imagine than my reflexes would have made me move my hand away. Just as well, because I think it was across my chest: I was holding the junction box in one hand (and maybe happening to touch a terminal) and then unscrewing another terminal with the other hand (happening to touch the shaft of the screwdriver). Having had a heart attack 10 years earlier, my heart may (I don't know) have been more sensitive than other people's to across-the-chest shocks.
