Thank you for your reply. I have been to my dentist who has examined my lip. There is a burst blood vessel there and the lump has subsided quite a lot. It is being reviewed next week and I have an appointment with my dermatologist at the beginning of November.
Hello,
This lump can be a fever blister, small cyst, hematoma, mucocele (if present on the inside of lower lip) or a benign growth of the lips. Since the lump is not changing in size, all these possibilities need to be evaluated.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
