Suggest Remedy For Recurring Pain And Sensitivity In Bunion Area Post Foot Surgery

In 2014 I had foot surgery to remove a severe bone spur--surgery included removal of cartiledge, insertion on bone that had to be pinned with a metal plate on top--this part of surgery was a success. The surgeon also reduced the size of a bunion (which did not hurt)--he could only reduce slightly because of the complexity of my other procedure. Now the bunion area is sensitive to the touch a looks like a small dot like callus has formed. I knew going into this surgery there would be some permanent numbness to my foot, which is a small price to pay for the not having the bone spur pain anymore. I am, however, perplexed by the lingering new bunion pain.
