Can I sue when I was injured while being handcuffed?

Q: I was running in the park on a dirt trail today. A police car pull up, a cop gets out of the car, tells me to get on my knees and to put my hands behind my back. I do what he says, He runs up twists my wrist and cuffs me. He keep twisting my wrist so the narrow part of the cuffs clamp around the wide part of my wrist. Now my wrists are cut and swollen and starting to hurt. 

It turns out a different cop pulled someone over. The person he pulled over ran into to the park. A diffrent cop thought I was the person. I was not arrested or given a summons. 

Should I look for a lawyer and file a lawsuit or is it a waste of time?

A: David's Answer: You would need some kind of medical proof that any injuries to your wrist were caused by the handcuffs being placed too tight. Thus, you'd first need to seek medical attention for your wrist. - David Bliven, Bronx Civil Rights attorney (www.blivenlaw.net)
