Any ideas as to why the first three fingers of each hand keep going numb?

Six months ago I was arrested for a broken tail light on my way home from church and handcuffed behind my back. Although I had never been handcuffed before, the cuffs seemed way too tight. However, the officer would not loosen them. When it was time to get up off the ground the officer jerked me by my right arm causing rotator cuff damage and a torn biceps tendon on that arm. Now, six months later, I'm starting to experience a painful "crik" in my neck when I turn it too quickly and also numbness in the first three fingers of each hand when I keep my arms in the same position for a while - like when I'm pushing my granddaughter's stroller. I'm wondering, because the handcuffs were pushing on the outsides of my wrists while the numbness seems to be on the inside of my wrists / hands / arms. Any ideas as to what can be causing the first three fingers of each hand to keep going numb? This is happening many times a day now. I've seen several doctors but they all seem to be blowing me off.
