What Causes Pain In Arms, Elbow And Shoulders Post Carpel Tunnel Surgery?

My wife, age 71 has been complaining lately of a achy pain in both arms from her elbow to her shoulder. The only thing she can think it might be from is Carpel Tunnel surgery that she had done about ten years ago. The first thing I thought of was a heart attack,but it is not just her left arm, it is both. Thank you Darl Mills My emails is; YYYY@YYYY
