In December of 2008 (or was it 2007? probably 2008) I was out at a bar and got elbowed in the face, specifically just to the right of my nose. By the next morning I had a black eye, and 3 or 4 of my teeth - the incisors and the canine - were hurting; they had a throbbing, sore pain, not the kind of pain that you experience when you have a cavity.
I went to the dentist, told him the story, and he did a couple tests (cold test, etc) and said that my teeth were fine. Most of the pain subsided within a few days.
After two months, the pain was completely gone, but there were still three problems, both effecting only my most front-right incisor: 1) if I tap on the tooth, it feels different. 2) If I bend down and turn my head upside down, as if to touch my toes, I feel a sensation that I can only describe as "blood pooling / going to my tooth". 3) If I press on the right side of my face, next to my nose, where I was hit, it also doesn't feel right.
So I went to my doctor, he checked for a broken bone in my face (though he did not do an x-ray), and said I was fine.
Now it has been over a year since this happened, and lately, as I stretch quite often, the odd sensations / feelings are happening more often. I have no idea what to call this, or how to research it, as I have such vague definitions of I feel.
I'm hoping that someone can point me in the right direction so that I can seek better help. I want to take care of this before it becomes worse of a problem.
