About a month ago, i was in an accident. My upper lip just below the nose was severely lacerated and my chin had some minor scrapes. My nose was slightly broken, but was not dislocated. I chipped a front tooth and broke a tooth in the back. My upper lip was tender but also somewhat numb for a bit, but the feeling is coming back. I still find I have difficulties with some words and have to concentrate to speak those words clearly. The letter "F" appears to be a little more difficult to pronounce. This all appears to be getting somewhat better; however, since the accident, my chin has been numb and does not feel like it has regained any feeling. It feels like there is a lump in my chin, but x-rays did not show that anything was broken and if I hold the lump, I can move it around on my chin. The worse injury appeared to be on my upper lip, but that is getting better. Is there an explanation for why my chin is still not getting better? Is there possible permanent nerve damage to the chin area? Thanks in advance for any help you can give me.
