What Causes Pain And Stiffness In The Arms After Administering Anesthesia?

I had my distal radial fracture reduction by 4 metal pins, had general anesthesia as well as a block on my whole arm. I experienced severe pain after anesthesia and suffered for three days until I got an appointment after weekend. One week ago otho surgeon removed the pins and now I cannot rotate my hand. I also have stiffness in my fingers, wrist and the whole palm of my hand. I have limited rotation, flexion, twisting and extension of the whole arm, which I suspect has been caused by the nerve block on my arm. My hand and wrist are still inflamed and swollen despite elevation and ice. I have a great fear this will be a permanent condition if I don t get proper medical care on this. Please give me your suggestions.
