Red Bumps on Inside Lower Lip

Red bumps on inside lower lip are commonly known as mouth ulcers. They are round or oval in shape with distinctive red sores inside the mouth and are quite painful. Although these bumps are painful, they are usually not a sign of any serious health problem and will disappear on their own within a week or two.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.


Medic8 and the National Health Service UK have listed many causes of mouth ulcers. They state mouth ulcers can be the result of medicines such as antibiotics or antihistamines. Acidic foods like coffee, large amount of juices and even eggs can also cause these bumps. Another cause is due to your stress, anxiety and workplace pressure. Immune system disorders such as HIV or changes to hormonal levels, especially during the menstrual cycle or pregnancy can also result in mouth ulcers.


According to Medic8, the first thing you will notice when you develop a mouth ulcer is a red bump, which later turns white and is inflamed around the edges. Mouth ulcers can make you irritable because of the constant pain and you may also experience difficulty while eating or drinking.

In most cases, mouth ulcers are temporary and disappear on their own within a week or two. However, if you are experiencing a lot of pain your doctor may recommend a number of treatments. According to, your doctor may prescribe a mouth rinse or oral medication to reduce inflammation and pain. There are also over-the-counter topical pastes that help relieve pain. Medic8 says putting ice on the affected area can also help bring temporary relief. Another option is to take a pain killer however, pain medicine can increase the number of ulcers.
