question: i took a cross check to the face about 2 months ago and ended up getting a whole right through my mouth requiring 10 outter and 6 inner stitches . to the right of the cut is what appears to be a large ball. I went to dermatologist today where he said he thinks it could be a keldoid scar excuse spelling but as i search the keldoid scars it appears to look nothing like them, just a fairly large ball type blister that wont go away. He injected cortizone this morning hoping to make it smaller.. Any ideas what this is?
