After arrest, I tried to hurt myself so they cuffed me for about 3 hours behind back (I fully understand the safety reasoning). After a couple hours I had to pee and couldn't feel my hands. Requests to urinate and/or loosen the cuffs were met with, as the kids say, "STFU." It's been 4 days and I haven't regained feeling in my right thumb. I also have a sizeable bruise on my left rib cage. As I said, I realize the safety precaution being taken, but have I any legal recourse for the potential nerve damage? Also, in your professional opinions and experience, for how long should one experience numbness??
