a Painful Red Lump Under the Left Armpit: Symptoms and Concerns - Oncology

More Info

---

The symptoms you are describing regarding the painful red lump under your left armpit raise several concerns that warrant further evaluation. Based on your description, it sounds like you may be dealing with an infected cyst or abscess, particularly given the presence of pain, drainage of foul-smelling fluid, and the history of the lump being present but smaller in size previously.

An abscess is a localized collection of pus that can occur in response to infection. The fact that the lump has increased in size and is now painful suggests that it may have become infected. The foul odor and the drainage of white fluid further support this possibility, as these are common characteristics of an infected area. If the lump was previously mistaken for a pimple, it could have been a sebaceous cyst, which can become inflamed or infected over time.

It is important to note that while many skin-related issues can be benign, the symptoms you are experiencing could also indicate other conditions, such as hidradenitis suppurativa, which is a chronic skin condition characterized by lumps in places such as the armpits and groin. This condition can lead to painful abscesses and can be associated with drainage and odor.

Given the ongoing nature of your symptoms, including the drainage and odor, it is crucial to seek medical attention. A healthcare provider can perform a physical examination and may recommend imaging studies to assess the lump further. They may also consider draining the abscess if it is confirmed to be infected, which can provide relief from pain and help resolve the infection. Additionally, a culture of the fluid may be taken to identify the specific bacteria involved, allowing for targeted antibiotic therapy.

In the meantime, it is advisable to keep the area clean and avoid squeezing or manipulating the lump further, as this can exacerbate the infection or lead to additional complications. Over-the-counter pain relievers may help manage discomfort, but they do not address the underlying issue.

In summary, the painful red lump under your left armpit, especially with the recent changes in size, pain, and drainage, suggests a possible infection that requires medical evaluation. Prompt attention from a healthcare professional is essential to determine the exact cause and appropriate treatment.
