Swollen lymph nodes in armpits: When to be concerned?


What are swollen lymph nodes?

Lymph nodes act as filters in the body’s immune system where they filter out potentially harmful substances from the body. Sometimes lymph nodes swell up to get rid of unwelcome cells or foreign particles, in response to an injury or infection. Swollen lymph nodes can be tender or painful when touched, and they may be present deeper in the body (Fletcher, 2021).

Why do lymph nodes swell in armpits?

Oftentimes swollen lymph nodes in armpits are a sign of infection, but it can also signal other medical conditions, such as an immune disorder or in rare cases cancer. Infection from various types of viruses and bacteria, or having a medical condition like rheumatoid arthritis or cancer can cause lymph nodes to swell.

Swollen lymph nodes in armpits may also develop after receiving an immunization, such as the COVID-19 vaccine, particularly after receiving the second shot of mRNA COVID-19 vaccines such as Pfizer-BioNTech or Moderna. The swelling subsides on its own in such cases (Swollen Lymph Nodes, 2022).

When should you be concerned?

Swollen lymph nodes that develop because of infection usually go away on their own when the infection clears away. However, if you notice any one of the following signs then you should seek medical assistance immediately (Staff, n.d.):

• When you notice that the lymph node swelling develops without any apparent reason
• When you notice that the swelling persists for more than 2 weeks or when the lump continues to enlarge
• When you notice swelling in more than one area, such as in the neck or groin area as well as in the armpit
• When you do not feel pain upon touching the lump
• When the swollen area feels hard and immobile upon touch
• When symptoms such as fever, night sweats, and sudden weight loss appear

How are large lymphnodes evaluated?

Ultrasound is a quick and painless method to evaluate large lymph nodes. Generally, a sonographer or radiologist can evaluate lymph nodes using a small hand held transducer. First, a bit of gel is applied to the skin on the body part to be examined. The probe is moved across the skin to create a picture on a computer screen. From that, they are able to look at the lymph node to better determine if the lymph node appears suspicious. The scan procedure takes about 10 minutes.
