Is My Armpit Lump a Cause for Concern? Symptoms and Risks

Are there any issues?

Excuse me, doctor: I would like to ask… I have a small hard lump in my armpit that I have noticed for several years.
Previously, when I went for an examination, the doctor told me it was a lipoma and said it wasn't a concern, only that it might hurt if I stayed up late.
Over time, I forgot about its existence.
However, in the past few days, it suddenly started to ache, and I also feel strange sensations in my chest area, like a sharp pain but not very intense.
Additionally, when I press on that hard lump, it hurts a lot.
Could there be any issues?

A sebaceous cyst typically does not cause pain and only feels like a hard lump when touched.
However, if there is a bacterial infection, it can become painful and appear red and swollen.
In more severe cases of infection, some cysts may become abscessed, requiring a physician to perform an incision and drainage procedure.
Therefore, if a sebaceous cyst is painful, physicians usually prescribe anti-inflammatory medication to the patient.
After a few days, once the inflammation subsides, they will generally recommend surgical excision of the entire cyst to prevent recurrence.
Since the cyst is currently inflamed, complete excision is not appropriate; only incision and drainage of the pus can be performed.

When it comes to lumps in the armpit, it's understandable to feel concerned, especially when there are changes in symptoms or sensations associated with them. Based on your description, you have a hard lump in your armpit that was previously diagnosed as a lipoma (a benign fatty tumor) and has been asymptomatic for years. However, you are now experiencing pain and unusual sensations in the area, which has prompted you to seek further clarification.

Firstly, it’s important to understand that while lipomas are generally harmless, any changes in the characteristics of a lump should be evaluated. The fact that you are now experiencing pain, especially if it is new or has changed in intensity, warrants further investigation. Pain can sometimes indicate inflammation or irritation in the surrounding tissues, and it could also suggest that the lump has changed in some way.

Here are several considerations regarding your symptoms:
1. Nature of the Lump: While lipomas are benign, other types of lumps can occur in the armpit area, including cysts, swollen lymph nodes, or even more serious conditions such as tumors. If the lump has become painful or has changed in size or consistency, it is essential to have it re-evaluated by a healthcare professional.

2. Associated Symptoms: You mentioned experiencing strange sensations in your chest along with the pain in your armpit. While these symptoms may not be directly related, they should not be ignored. Chest discomfort can arise from various causes, including muscular strain, nerve irritation, or even issues related to the heart or lungs. It’s crucial to discuss these symptoms with your doctor, especially if they persist or worsen.

3. Inflammation or Infection: Sometimes, lumps can become inflamed or infected, leading to pain and discomfort. If the lump is tender to touch and you notice any redness or warmth in the area, this could indicate an infection that may require treatment.

4. Lymphatic System: The armpit area contains lymph nodes, which can swell in response to infections or other health issues. If you have had any recent infections or illnesses, this could explain the changes in your symptoms. Swollen lymph nodes can be painful and may require further evaluation to rule out any underlying conditions.

5. Follow-Up Care: Given the changes in your symptoms, it is advisable to schedule a follow-up appointment with your healthcare provider. They may recommend imaging studies, such as an ultrasound or MRI, to assess the lump more thoroughly and determine if any further action is needed.

6. Self-Monitoring: Keep track of any additional symptoms that may arise, such as fever, weight loss, or changes in your overall health. This information can be valuable for your healthcare provider in determining the next steps.

In summary, while your lump may have been previously diagnosed as a benign lipoma, the recent changes in pain and sensation are significant enough to warrant further evaluation. It is always better to err on the side of caution when it comes to health concerns, especially when there are new or worsening symptoms. Please consult with your healthcare provider to discuss your symptoms in detail and to determine the appropriate course of action. Your health and peace of mind are paramount, and addressing these concerns proactively is the best approach.
