Encountered facial tightness and numbness during TBI recovery?

Haven't had that problem, but, when I was hit by a bicylist in 2014, I found (eventually, through reading) that my unconscious has been blocking my memory of the accident. I remember seeing my right foot about to touch down on the crosswalk, followed immediately by blackness and muffled sounds for just a moment, and then finding myself seated cross-legged in the middle of the street with people around me who were not there when I stepped into the crosswalk. It took me three years of reading various sources to figure out what had happened. When I "came back into the world," as I think of it, I found myself sitting there with a cop standing over me to my right and a puddle of blood to my left, which I somehow knew was mine. In front of me, across the street, were two men in yellow construction clothing who were looking at me until I looked back at them, then they turned their heads away. I looked up at the cop and said, "What happened to me?" He said, "You were hit by a bicyclist." I said, "Oh, yeah!" as if I already knew. The sun was warm on my face and I felt no pain. Behind me were people, out of sight, busy doing something (getting ready to put me on the ambulance, as it turned out). The cop asked me if I remembered "the man who came to" help me. I said that I didn't remember anything between stepping into the crosswalk and "coming back to consciousness" sitting up. He said, "Are you sure you don't remember the man who came to help you?" Again, I said I didn't, referring, again, to having been unconscious, which is what I thought had happened for the next three years. It seemed that way to me, as I had no memory of what happened before and after the impact. Meanwhile, the bicyclist appeared, standing beside his somehow undamaged bicycle, smiling at me. He came over to me, bent down and said in a hushed voice, even with the cop standing beside me, "I sure am glad you're still alive!" I looked up at him and said, "Yeah, me, too." His smile vanished and was replaced by a look of fear, then he hurried back to his bicycle. At just that moment, the ambulance crew were ready for me and there was no further conversation. The ambulance driver told me "You were perseverating." Not being familiar with the term and too embarrassed to say so, I didn't ask him what it meant. So, I looked it up online after I was home again. It means I was saying the same words over and over, out of context with the original conversation. So, that was my main clue that I hadn't been unconscious, but it still took me a while to figure it out. So, if my unconscious knows what happened to me and is blocking my memory of it, that's fine with me. If I did remember it, it would be replaying in my mind over and over again for the rest of my life!
