Lip issues

I scraped my nail against my lip very hard.
It swelled up before, but after it went down, there is now a round bump in the middle of my upper lip.
It has been 4 months and it still hasn't gone away.
What could be the problem? Should I see a doctor? I can still feel it when I touch my lip, and it hasn't disappeared.

Dear readers: 1.
Both the lips and skin are protected by a thick layer of keratin or mucous membrane that guards against bacterial infection.
If this barrier is breached, bacteria from the skin or oral cavity may invade, leading to infection (redness, swelling, heat, and pain).
2.
Scratched lips heal quickly and flatten out, so there is no need for excessive worry.
Additionally, applying lip balm can help protect the newly formed skin.

More Info

When it comes to a persistent lip bump that has lasted for four months without resolution, it is advisable to seek medical attention. While many lip bumps can be benign and may resolve on their own, the duration and characteristics of the bump you described warrant further evaluation by a healthcare professional.

There are several potential causes for a persistent bump on the lip, including:
1. Mucoceles: These are fluid-filled cysts that can occur when a salivary gland duct is blocked. They often appear as painless, swollen areas and can sometimes resolve on their own, but if they persist, they may need to be surgically removed.

2. Fibromas: These are benign tumors that can develop in response to irritation or trauma. If the bump is firm and does not change in size, it could be a fibroma, which may require excision if it causes discomfort or cosmetic concerns.

3. Keratotic lesions: These can occur due to chronic irritation, such as from biting or trauma. They may appear as raised, rough patches on the lip and can be mistaken for warts or other growths.

4. Infections: Viral infections, such as herpes simplex, can cause lesions on the lips. If the bump is associated with pain, redness, or other symptoms, it may indicate an infection that requires treatment.

5. Skin cancers: Although less common, persistent lesions on the lip can sometimes be indicative of skin cancer, particularly in individuals with risk factors such as fair skin, sun exposure, or a history of skin cancer. Basal cell carcinoma and squamous cell carcinoma are the most common types that can occur on the lip.

Given that the bump has persisted for four months, it is important to have it evaluated by a healthcare provider, preferably a dermatologist or an oral surgeon. They can perform a thorough examination and may recommend a biopsy if there is any suspicion of a more serious condition.
In the meantime, it is advisable to avoid any further trauma to the area, such as picking at the bump or applying irritants. Keeping the area clean and avoiding any known irritants can help prevent further complications.

In summary, while many lip bumps are benign, the persistence of your bump for four months is a clear indication that you should seek medical attention. A healthcare professional can provide a proper diagnosis and recommend appropriate treatment options based on the specific characteristics of the bump. Early evaluation is key to ensuring that any potential issues are addressed promptly and effectively.
