Im not sure if this is the place to find my answers, but Ill try. Following a crown prep, that area continued to feel odd, heavy, for months. It seemed to be the area the shot went in,but its hard to pinpoint. After three months, the sensation eased a bit and now it seems to come and go. Is this a pattern of nerve healing? It seems affected by weather and when i had a virus, etc. It was never pain, only this heavy feeling.
