Painful Lumps in the Armpit: When to Seek Medical Attention

There is a lump in the armpit?

Hello doctor, recently I have noticed a 0.5 cm dark hard lump under my left armpit, which is painful when pressed, and it feels like the lump is larger internally.
1.
Since childhood, I have often experienced lymphadenopathy due to irregular sleep patterns or stress, usually in elongated shapes up to about 1.5 cm, and these lumps were larger than this one, but I have never seen a dark coloration.
2.
I have a history of excessive sweating in my armpits (though it has improved recently), and six months ago, there was a suppurated sweat gland cyst near the lump, which was cleaned at a clinic and treated with medication, with no recent recurrence.
3.
Two weeks ago, I had severe inflammation due to an impacted wisdom tooth and gingivitis, which led to pus formation; I had it cleaned at the dentist and completed a course of antibiotics, but since I have not yet had the tooth extracted, there is still slight inflammation.
I would like to ask if I should seek medical attention for this condition promptly or if I can observe it further? Are there any methods to alleviate the symptoms or self-diagnose?

It is likely folliculitis or a sebaceous cyst.
It is recommended to observe for a few days (get plenty of rest, drink plenty of water, and keep the underarm area dry and clean).
If there is no improvement, consider seeing a dermatologist or a plastic surgeon.

More Info

When it comes to the presence of painful lumps in the armpit, it is essential to approach the situation with caution and awareness of potential underlying issues. Based on your description, you have a 0.5 cm hard lump that is painful upon pressure and appears to have a darker coloration. Given your medical history of lymph node swelling, sweat gland issues, and recent dental infections, it is prudent to consider several factors before deciding on the next steps.

Understanding the Symptoms
1. Lump Characteristics: The fact that the lump is painful and has a darker appearance could indicate several possibilities, including an inflamed lymph node, an infected cyst, or even a benign tumor. The pain suggests that there may be inflammation or irritation in the area, which could be due to infection or another underlying condition.

2. Medical History: Your history of lymph node swelling and previous issues with sweat gland cysts adds complexity to your current situation. Lymph nodes can swell in response to infections, inflammation, or other stimuli, and the fact that you have had a recent dental infection could be contributing to the current symptoms.
3. Recent Infections: The recent dental infection and the treatment you received could also play a role in your current symptoms. Infections can lead to localized swelling and pain, and if the infection was systemic, it could potentially affect nearby lymph nodes.

When to Seek Medical Attention
Given the symptoms and your medical history, it is advisable to seek medical attention sooner rather than later. Here are some indicators that warrant immediate evaluation:
- Persistent Pain: If the pain worsens or does not improve over the next few days, it is essential to consult a healthcare provider.

- Increased Size: If the lump increases in size or if new lumps appear, this could indicate a more serious issue that needs to be addressed.

- Systemic Symptoms: If you experience fever, chills, or other systemic symptoms such as fatigue or malaise, these could indicate an infection that requires treatment.

- Changes in Appearance: If the lump changes in color, becomes more tender, or if you notice any discharge, these are signs that you should seek medical advice.

Self-Diagnosis and Management
While waiting for a medical appointment, you can take some steps to monitor your condition:
- Observe Changes: Keep track of any changes in the lump's size, shape, or pain level. Note any new symptoms that may arise.

- Warm Compress: Applying a warm compress to the area may help alleviate discomfort and promote drainage if the lump is related to a cyst or localized infection.

- Avoid Irritation: Try to avoid any activities that may irritate the area, such as tight clothing or excessive movement that could exacerbate the pain.

Conclusion
In summary, while it may be tempting to wait and see if the lump resolves on its own, given your medical history and the characteristics of the lump, it is advisable to seek medical attention. A healthcare provider can perform a thorough examination, possibly including imaging studies or a biopsy, to determine the exact nature of the lump and recommend appropriate treatment. Early intervention can help prevent complications and ensure that any underlying conditions are addressed effectively.
