Hard lump at the corner of the mouth?


On May 18, I noticed a hard lump located diagonally below the right corner of my mouth.
I assessed that starting from the evening of May 19, it began to hurt when pressed, measuring about 0.8 cm.
I evaluated that on May 20, it was painless throughout the day, but the lump was still present.
By nightfall, I suddenly felt tightness and slight pain in the muscles from my right ear to the lump.
I was uncertain and panicked.
On the morning of May 21, my thermometer showed a temperature of 37.3 degrees Celsius, and I felt my body was warm.
I went to the family medicine department at the hospital in the morning, where I was prescribed antibiotics and medications for joint and nerve pain, as well as stomach medication.
After taking the medications, I still did not feel any improvement.
I forgot to mention to the doctor that a whole area of muscle felt very tight.
The doctor informed me that I had a cavity in my right teeth.
In the evening, I went to the dental clinic to have the cavity filled.
I would like to ask if there are any cases of tumors growing on the face, as I am really worried and quite upset.

Miss Baby: Your description sounds more like inflammation, and it might indeed be caused by a cavity.
Thank you!

More Info


Understanding hard lumps at the corner of the mouth can be concerning, especially when accompanied by pain, tightness in the surrounding muscles, and fever. Based on your description, it seems you have been experiencing a hard lump near your right mouth corner for several days, which has caused discomfort and has led to a visit to your healthcare provider.
Firstly, it’s important to recognize that hard lumps in the oral cavity or surrounding areas can arise from various causes. Some common reasons include:
1. Infections: An abscess or localized infection can lead to the formation of a hard lump. This is often accompanied by pain, swelling, and sometimes fever, as your body fights the infection. The fact that you were prescribed antibiotics suggests that your doctor suspected an infectious process.

2. Cysts: These are fluid-filled sacs that can develop in various tissues, including the oral cavity. They can feel firm and may cause discomfort if they become inflamed or infected.

3. Fibromas: These are benign tumors made of connective tissue that can appear as hard lumps in the mouth. They are generally painless unless they become irritated.

4. Salivary Gland Issues: Problems with the salivary glands, such as stones or infections, can also lead to lumps and discomfort in the mouth area.

5. Dental Issues: As your dentist noted, cavities or other dental problems can lead to localized swelling and pain. The tightness in your muscles could be a response to pain or discomfort in the area.

6. Tumors: While it’s understandable to be concerned about tumors, it’s important to note that not all lumps are malignant. However, if a lump persists, changes in size, or is associated with other concerning symptoms (like significant pain, difficulty swallowing, or unexplained weight loss), further evaluation is warranted.

Given your symptoms of muscle tightness and fever, it’s crucial to follow up with your healthcare provider. You mentioned that you forgot to inform your doctor about the tightness in your muscles. This is an important detail, as muscle tension can indicate that your body is responding to pain or discomfort, possibly related to the lump or an underlying issue.

If your symptoms do not improve with the antibiotics and pain management prescribed, or if you notice any changes in the lump (such as increased size, color changes, or persistent pain), it would be wise to seek further evaluation. This may include imaging studies (like an ultrasound or CT scan) or a referral to a specialist, such as an oral surgeon or an ENT (ear, nose, and throat) doctor, for a more thorough examination.

In summary, while it’s natural to worry about the possibility of a tumor, many lumps in the mouth area are benign and treatable. It’s essential to maintain open communication with your healthcare provider, report any new or worsening symptoms, and follow their recommendations for further evaluation and treatment. Your health and peace of mind are paramount, so don’t hesitate to seek additional medical advice if needed.
