ankle fusion and cuttingof the fibia

had fuson of my right ankle in July ’03.
This was after a sever break and 6 surgeries to repair 11 breaks in the ankle joint.
DId alright (so-so) for 5 years.
Arthirtis began to realy eat me up. So I opted for the fuison upon recommendation from my surgeon.
Here’s the question/thing.
Little or no pain anywhere in my foot EXCEPT in the area between the fusion and the fibia. Now, lilke most fuisons I’ve read about, the surgeon did remove about 2 inches of the fibia about 3″ about the outside point of the ankle.
I’m now having shooting pains in that area.
Since the fibia serves no purpose after a fusion, why isn’t the lower piece removed during the surgery?
I can honestly say, mine has almost grown back together.
Is this pain normal, or should I go back and see about having the remaining lower part of the fibia removed?
I need help.
I’m 53 and a prison guard and on concrete all day.
Not old enuff to retire but can’t take much more of the constant pain…..
