I have a very old injury (13yrs) to my calf and ankle. I have had no feeling in my leg from back of knee to ankle all this time. In the last couple of days, I have re-injured my ankle (I think) it is swollen and very sore. Today, for the first time, I have feeling in the back of this leg - the muscle is sore and tight. Could this mean Im getting the feeling back? Have I just severly injured the leg? I also have gained feeling at the surface - I can feel something touching the skin.
