question: I am Manoj from chennai. For the past 3 weeks i am having problem with my lips. I have the habit of bitting my lips and now the problem is the color of my lower lips changing to white :( (when i close my lips its not visible) I recently consulted doctor in local. He said that this comes with no reason and he asked me whether i smoke. I never touched cigarette . I am very sad and this reducing my confidential level when i speak to others. please help me!! Thank you Sir/Madam
