Could Your Lymph Nodes Be Causing That Painful Bump? - Internal Medicine

It sounds like you are experiencing some concerning symptoms with the painful bump under your armpit, and I understand how worrying this can be. Based on your description, there are a few potential explanations for the pain and swelling you are experiencing.

Firstly, the bump you felt could be a swollen lymph node. Lymph nodes can become enlarged for various reasons, including infections, inflammation, or even malignancies. Given that you mentioned waking up with a sore throat, it is possible that your body is responding to an infection, such as a viral or bacterial illness. When the body fights off an infection, the lymph nodes in the area can swell as they work to filter out pathogens and produce immune cells.

In your case, the pain and swelling under your armpit could be related to a localized infection, possibly in the arm or breast area, or it could be a response to a systemic infection, such as a cold or flu. The fact that you have a sore throat suggests that your body might be dealing with an upper respiratory infection, which can lead to swollen lymph nodes in the neck and armpit.

Another possibility is that the bump could be a cyst or an abscess. Cysts are fluid-filled sacs that can develop in various parts of the body, including the armpit. An abscess, on the other hand, is a collection of pus that can occur due to an infection. Both conditions can cause pain and swelling, and they may feel tender to the touch.

It is also important to consider other factors that could contribute to your symptoms. If you have a history of skin infections or conditions such as hidradenitis suppurativa, this could also explain the painful bump. Additionally, if you have been experiencing any recent injuries or trauma to the area, this could lead to localized swelling and pain.

In terms of what to do next, it is advisable to monitor the bump closely. If it continues to grow, becomes increasingly painful, or if you develop additional symptoms such as fever, chills, or persistent sore throat, you should seek medical attention. A healthcare provider can perform a physical examination and may recommend imaging studies or laboratory tests to determine the underlying cause of the swelling.

In summary, while your symptoms could be related to an infection, it is essential to have a healthcare professional evaluate your condition to rule out any serious issues. Early intervention can help address any underlying problems and provide you with peace of mind. If you have any further questions or concerns, please do not hesitate to reach out to a medical professional for guidance.
