Painful Lumps in the Armpit: Causes and Concerns - Obstetrics and Gynecology

When it comes to painful lumps in the armpit, there are several potential causes that one should consider. The presence of small, round lumps that are tender to the touch and resolve on their own can be indicative of a few different conditions, but it is essential to consult a healthcare professional for an accurate diagnosis.

One common cause of lumps in the armpit is swollen lymph nodes. The lymphatic system plays a crucial role in the body’s immune response, and lymph nodes can become enlarged due to infections, inflammation, or other underlying conditions. If you have had any recent infections, such as a cold or skin infection, this could explain the swollen lymph nodes. Typically, these lumps will be tender and may fluctuate in size as the body fights off the infection.

Another possibility is the development of sebaceous cysts. These are benign lumps that form when sebaceous glands become blocked, leading to the accumulation of sebum (an oily substance). Sebaceous cysts can be painful if they become inflamed or infected, and they often feel like small, movable lumps under the skin. They can appear anywhere on the body, including the armpit.

Additionally, lipomas, which are benign tumors made of fat tissue, can also present as soft, movable lumps in the armpit area. These are generally painless and slow-growing, but if they become large or press on nearby structures, they may cause discomfort.

In some cases, painful lumps in the armpit could be related to more serious conditions, such as infections (like abscesses), or even malignancies. While it is less common, certain types of cancer can present as swollen lymph nodes or lumps in the armpit area, particularly lymphomas or breast cancer that has spread to nearby lymph nodes.

Given that you have noticed a change in the size and frequency of these lumps, it is advisable to seek medical evaluation. A healthcare provider may perform a physical examination and may recommend imaging studies, such as an ultrasound, to better understand the nature of the lumps. In some cases, a biopsy may be necessary to rule out any serious conditions.

In summary, while many causes of painful lumps in the armpit are benign and self-limiting, it is crucial to monitor any changes in size, pain level, or associated symptoms. Early evaluation by a healthcare professional can help ensure that any underlying issues are addressed promptly and appropriately. If you experience additional symptoms such as fever, night sweats, unexplained weight loss, or persistent pain, these should be communicated to your healthcare provider as they may indicate a more serious condition.
