i had surgery on the top of my foot over a year ago. the doctor shaved off a bone spur that had arisen from the top of my foot rubbing on shoes (i have high arches and little foot padding). now i'm starting to feel with the slightest compression, cold shooting sensationd that move forward to the toes. this is the right foot. the doctor said he stitched the nerve to the side after he shaved off the bone, but another doctor, and myself, can feel the nerve(s) near the center and a little to the right. does anyone know what this could be? why i could be feeling this sensation? can i do anything to stop this sensation? should i be worried?
