Swollen Upper Lip

Swollen upper lip is a condition when the upper lip of a person gets bigger in size along with a feeling of numbness and pain in it. The swollen region can be either a part of the upper lip, the whole lip, or the inside portion of the lip. Sometimes the swelling happens overnight and the person is unable to find the reason. This problem is common in adults as well as in babies. The swelling in the upper lip is usually caused by different factors that can be directly and indirectly linked to the lip. The swelling can sometimes be seen as one of the symptoms of a different disease.

Symptoms of Swollen Upper Lip

  • Numbness and Tingling: In some cases the swollen lip might feel numb and have a little tingling sensation to it. This usually happens when the whole lip is swollen and you cannot feel anything while touching or moving your mouth.
  • Increase in the size of lip: Swelling in itself means that the lips get filled with fluids and become bigger in size. But in some cases, the swelling comes overnight and makes the lip very large. This can increase the size of the lip in a particular area like just below the nose or the whole lip.
  • Pain: With the swelling and numbness comes pain. There is a slight pain in some cases on the swollen lips and the areas around it. You might also feel some tingling sensations. The pain might exceed if the area is touched or some force is applied to it.

Causes of Upper Lip Swelling

There is not one but many causes for swollen upper lips. The swollen upper lip may sometimes be the disease in itself but mainly is a symptom of other diseases. Upper lip swelling might happen for no reason at times and might go away with time. Some of the biggest reasons for this condition are:


swollen upper lip from injury

The most common cause of a swollen lip is a lip injury or a trauma. It might happen when the lip gets hit by a sharp or a blunt object or gets bruised due to any activity like sports or biting the lip or playing musical instruments. This leads to bruising and swelling. This swelling is painful and usually happens at one part of the lip that has been injured. It usually goes overtime on itself or on applying hot and cold compress on it. No special medical assistance is required unless there is a cut on the lip.


swollen upper lip from allergy

Allergy is the second most common causes of the swollen upper lip. Many people are allergic to certain kinds of foods, medicines, pet hair or dander, different lip cosmetics etc. If you suddenly start having swollen lips, then allergies are the most common reason. If you apply a certain type of lip care product or sleep on a bed with animal dander, your lips will swell overnight and you will have swollen lips in the morning. Similarly, after eating the food or medicine that your body is allergic to, the lip will start to swell as a natural response of the body to a foreign substance. Anaphylaxis which is one of the most dangerous allergy mostly caused by foods or medicines also leads to the swollen upper lip. The allergy can be identified easily because apart from the lip, it will affect the other parts of the body as well. This allergy requires immediate medical assistance since it is life threatening.

Surgery(Rhinoplasty or Lip Augmentation)

Rhinoplasty, in common terms, is a nose job which is done to fix various deformities in a person’s nose. After rhinoplasty, there might be a slight swelling below the nose in the area between the nose and the lips. This goes with the time as the operated part heals but can sometimes stay for a longer period of time when the surgery has gone wrong. Same is the case with lip augmentation which is done in different ways such as surgery and lip injections. The chemicals present in the injections are not suitable for all types of people and lead to reactions and hence swollen upper lip.

Cold Sores

The cold sores are very painful and cause the upper lip to swell. They are the symptoms of the herpes virus the HSV or the HIV that is the AIDS virus. These sores usually take a lot of time to heal i.e. from six to seven days to about two to three weeks. These should get checked immediately and medical assistance should be taken.
