This may have nothing to do with my microdiscectomy (Nov.14, 08)but...in the past few days I've had intermittent periods of not being able to flex or extend my foot without strong, sharp pain. It will be there for a few minutes, then all of a sudden, it's gone..only to come back again in a few minutes. It can get to the level that I can barely walk. Could this be the "dead foot" I've heard about? I assumed that meant that the foot would fall asleep for no reason. Although I do have some numbness left in my foot this is PAIN that seems to be deep in my ankle...I thought maybe I injured it through PT, but why would it come and go like that...One more odd occurrence in a long series of them...thanks for the insight!
