Understanding lip lesions can be quite complex, as they can arise from a variety of causes, each with its own implications for treatment and management. Based on your description, it seems you have experienced a progression of symptoms that started with a sore or ulcerated area on your lip, followed by the appearance of a white bump that has since changed in size and shape. Let’s address your questions one by one.

1. What could this be?
The initial sore on your lip could have been an aphthous ulcer (also known as a canker sore), which is a common and usually benign condition. These ulcers can be painful and may take several days to heal. The subsequent white bump you described could be a number of things, including a healing ulcer, a mucous cyst, or even a benign growth such as a fibroma. The fact that it was not painful and changed in size suggests that it might not be an infectious process, but rather a reactive lesion. However, without a physical examination, it is difficult to provide a definitive diagnosis.

As for the concern about transmissibility, most lip lesions like canker sores are not contagious. However, if the lesion were caused by a viral infection, such as herpes simplex virus (which can cause cold sores), then it could be contagious, particularly during an outbreak.

2. When to seek medical help?
If the white spot persists for more than two weeks without improvement, or if you notice any additional symptoms such as increased pain, swelling, or changes in color, it would be advisable to seek medical attention. Persistent lesions in the mouth or on the lips can sometimes indicate underlying conditions that require treatment, including infections or, in rare cases, precancerous changes.

3. Which specialist to see?
For issues related to lip lesions, you would typically start with a visit to a dentist or an oral surgeon, as they specialize in conditions affecting the mouth and surrounding areas. If there are concerns about the lesion being related to a systemic issue or if it does not resolve, a referral to an ear, nose, and throat (ENT) specialist may also be appropriate.

In summary, while many lip lesions are benign and self-limiting, it is important to monitor your symptoms closely. If you notice any changes or if the lesion does not resolve, do not hesitate to seek professional evaluation. Early intervention can often lead to better outcomes, especially if there is an underlying condition that needs to be addressed. Remember to maintain good oral hygiene and avoid irritating the area further, as this can help promote healing.
