Bone spur on top of foot

I had ankle surgery over a year ago and it still bothers me. Something is also clicking in my foot. It hurts at times and is stiff at times as well. 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. My question is: Will the ankle exercises help the bone spur disappear or will I need to get surgery to remove the bone spur?

Any advice would be greatly appreciated. Thank you.
