I didn't realize this, but apparently if you struggle too much in handcuffs, you can injure a nerve on your wrists and lose feeling in your thumb. I don't think I injured it that badly, but I did remove the fuzzy part of the handcuffs me and my boy were using... and I liked struggling... BUT NOW MY THUMB IS ALL TINGLY. Whoops! Says it takes 2-12 months to recover from this type of injury and the nerve should not be re-injured again 😔 I just started liking the idea of handcuffs, what are some other options that won't injure me the same way?
