Just wondering if it's possible to have long-term injuries from correct/incorrect application of an arm in guillotine. Aside from choking someone out, is it possible to do damage to someone. I put someone in it and I guess he let his pride take over and didn't tap out so I might've left it on longer than I should have. I didn't choke collapse his esophagus but just held him it for a while. Maybe I should've just started the choke and made forced the tap out.
