I can’t unfeel it now and it’s making me uncomfortable.

I’m not the only one right?.

People said they groped their arms trying to perceive the switch, or simply stated that it looked painful.

So my bones are stuck' in the twisted motion, said one user.

Can’t rotate my wrist at all.

For those who are able toappreciate your weird twisty and untwisty bones!
