I had tingling in my left arm and fingers on and off for the first 4 months of my recovery. For some reason it worried me more then the other symptoms. Then after a while it started to be less and less and after 5 months completely gone. This is the only symptom I can say that has actually come and gone since my injury.
Now if only the other symptoms could disappear like that I would be the happiest guy in the world! I'm sure everyone else here feels the same.
