What causes a bump on the lip after biting or oral contact?

Hello,

Welcome to icliniq.com.

I understand your concern.

Based on what you described, it sounds more like a mucocele, which is a harmless bump caused by damage to a small salivary gland, often from biting your lip. This seems likely because the bump appeared right after you bit your lip, it is soft and painless, and it grew in size before flattening out. It is also located on the inside of your lip near the corner, a common area for mucoceles, and you did not experience any tingling, burning, or a group of blisters.

It is probably not herpes at this point because oral herpes usually begins with a tingling or burning sensation, followed by the appearance of small, painful blisters that later burst and form a crust. The first outbreak can also cause flu-like symptoms such as tiredness, fever, or swollen glands. Additionally, you noticed the bump just hours after contact, which is too soon for herpes symptoms to appear; they usually take between two to twelve days.

To help with healing, do not pop or pick at the bump, as that can cause irritation or infection. Instead, rinse your mouth gently with warm saltwater (one teaspoon of salt in a cup of water) two to three times a day. Avoid foods that are spicy, acidic, or crunchy, as they might make the area more irritated. In many cases, mucoceles shrink or go away on their own within one to two weeks. However, if it does not heal or keeps coming back, a dentist or doctor can remove it safely.

You should be more concerned about herpes if you notice a cluster of small, painful blisters, if the sore becomes crusted or starts to spread, or if you experience flu-like symptoms such as fever or swollen glands. If any of that happens, it is important to visit a clinic for a swab test or blood test to check for herpes. Let me know if you would like help finding a low-cost clinic or testing center near you.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.
