Wow! I have the same thing!! I have Lupus which is an immune disorder and my neice was telling me that I should be getting Vit. B12 shots!! Thank you for writing you probably have helped me more than you know! I have been feeling really sick. When you have a chronic illness you tend to brush off things because you can't go to the doctor every time something happens! I just figured my lips were really dry, but it was weird why they were blistered on the top and would cycle like that. Thanks so much and I will keep you posted!

Hi,
How are you? Most mouth sores such as in your case are caused by: accidental trauma ( bites or burns from hot food or drinks); infection, hormonal changes, immune system related, stress or from low levels of vitamin B12 or folate. Less commonly, mouth sores can be a sign of an underlying illnes or reaction to a medication. Continue with rubbing vit B12 on your lips and if it persists, have this evaluated further for proper management and to rule out conditions mentioned.
Take care and regards.
