Hello, on Wednesday (2-17-2016) I had all 4 of my Wisdom teeth extracted plus 4 of my premolars in order to make room for braces. I stopped bleeding about a day after the extraction and swelling has been gradually and slowly going down since Friday, but there is a hard lump inside my left cheek that hasn't gone away. It is literally on the inside of my cheek as I felt on the inside of my mouth to confirm. I contacted my oral surgeon and he said that it's probably bleeding, it doesn't hurt when I press on it unless I put a great amount of pressure on it. I am just looking for a second opinion, is it really bleeding or could it be something else. Any help would be appreciated!
