question: I had a right wrist replacement approximately 4 years ago and have begun having severe pain in the arm where the device is . At times it will lock up and feel as if I cannot lift a cup without dropping it . Almost feels a if the tendons are torn or wrapping around the prosthetic device or that it is broken approximately half the way up. I also am having spasms of my fingers 2 of them and my thumb that won t release for up to a minute, I have had 3 cervical spine surgeries also and don t know if this has anything to do with this I a fused at c2 thru 7 ??? Could it be broke ? I am only supposed to lift more than 3 lbs with that hand and know at times I have lifted more than this as i am right handed ad its very difficult to not lift ...seems to be worsening is this a normal side effect ??? Any help would be appreciated .
