What are the common causes of swollen lymph nodes in the armpit. How can you identify swollen lymph nodes. When should you seek medical attention for swollen lymph nodes in the armpit. What treatments are available for swollen lymph nodes.

Understanding Lymph Nodes and Their Function

Lymph nodes play a crucial role in our body’s immune system. These small, bean-shaped structures are part of a complex network that helps filter out harmful substances and fight infections. But why do lymph nodes sometimes swell, particularly in the armpit area?

Swollen lymph nodes, also known as lymphadenopathy, occur when these structures enlarge as they work harder to filter out unwanted cells from the lymph. This fluid carries oxygen to cells and transports waste products away, while also containing white blood cells that combat infections.

How do lymph nodes function in the immune system?

Lymph nodes act as filters for the lymphatic system. They trap bacteria, viruses, and other pathogens, allowing white blood cells to destroy them. When an infection or injury occurs, nearby lymph nodes may swell as they increase their filtering activity. This swelling is often more noticeable in certain areas of the body, including the neck, armpits, and groin.

Common Causes of Swollen Lymph Nodes in the Armpit

Swollen lymph nodes in the armpit can be attributed to various factors, ranging from minor infections to more serious health conditions. Understanding these causes can help you determine when to seek medical attention.

• Influenza (flu)
• Infectious mononucleosis (mono)
• Varicella-zoster virus (chickenpox)
• Measles
• Mumps
• Rubella
• HIV

Bacterial Infections

Bacterial infections can also cause lymph node swelling in the armpit area. Some common examples include:

• Cellulitis
• Lyme disease
• Chlamydia
• Syphilis
• Tuberculosis

Recognizing Symptoms of Swollen Lymph Nodes

Identifying swollen lymph nodes in the armpit is crucial for early detection and treatment of potential underlying conditions. But how can you tell if your lymph nodes are swollen?

What are the signs of swollen lymph nodes in the armpit?

Swollen lymph nodes may present with the following symptoms:

• A visible lump or enlargement under the skin

• Fever
• Swelling in the liver, spleen, or both
• Sore throat
• Body aches
• Headaches

While mono usually resolves on its own within 2-4 weeks, some individuals may experience symptoms for a longer period. Rest, hydration, and over-the-counter pain relievers can help manage symptoms during recovery.

Bacterial Infections and Swollen Lymph Nodes in the Armpit

Bacterial infections can also cause lymph node swelling in the armpit area. Two notable examples are cellulitis and Lyme disease.

Cellulitis

Cellulitis is a skin infection that occurs when bacteria penetrate the skin and infect deeper layers, often through an area of broken skin.

How does cellulitis manifest in the body?

Common symptoms of cellulitis at the infection site include:

• Pain and swelling
• Skin sores
• Warm skin
• Redness (may be less apparent in people with dark skin tones)
• Hardening of the skin
• Fluid collection under the skin

Additional symptoms may include fever, chills, body aches, muscle and joint pain, vomiting, nausea, and fatigue. Cellulitis is typically treated with antibiotics, and severe cases may require hospitalization for intravenous antibiotic administration.

Lyme Disease

Lyme disease is transmitted through the bite of certain tick species and can cause swollen lymph nodes as an early symptom.

What are the early signs of Lyme disease?

Early symptoms of Lyme disease, which may appear 3-30 days after the tick bite, include:

• A circular, bull’s-eye rash at the bite site
• Fever
