Bone spur on top of foot

I had ankle arthroscopic surgery and a Brostrum repair on April 8, 2008. For the past few months, I have been experiencing pain in my ankle well over a year after surgery.

I saw my ankle surgeon a couple of weeks ago and I had just found out that I have a bone spur on the top of my right foot (the same foot and ankle that I had surgery on in April 2008). He told me to do some ankle exercises to relieve some of the pain. He didn't do anything with the bone spur yet. I go see him again October 15. My question is: Will the ankle exercises help the bone spur disappear or will I need to get surgery to remove the bone spur?

Is surgery the only option to remove the bone spur or will exercising my foot help it disappear?

Any adivce would be greatly appreciated. Thank you.
