Hello, about a year ago, I bit a small part of my upper lip. It usually shouldnt be a problem because it heals and closes, but in my case its not doing that. Every 3-4 days, a new layer of skin forms, and starts pealing, and eventually peels off completely. After another 3-4 days a new skin layer forms again, then start peeling, and goes away completely also. This has been going on for 1 year, there is no bleeding associated with it, but this wound just won`t heal and close, and a new skin layer forms and peals every 3-4 days. I tried using every medical lip stick I know off and all sort of things but they are not working. What is the solution?
