Understanding Swollen Lymph Nodes and Their Causes

The lymphatic system plays a crucial role in maintaining a healthy immune response. Lymph nodes, small bean-shaped glands, are part of this system, responsible for transporting lymph fluid, nutrients, and waste products between tissues and the bloodstream. Swelling of these glands, often referred to as swollen lymph nodes, can occur due to infections, injuries, or sometimes tumors near the nodes.

Since lymph nodes are essential for fighting infections, swollen glands in the neck should be addressed promptly. Common causes include infections or growths in nearby organs like the lungs, breasts, or abdomen. Swelling in neck lymph nodes can also result from infections in the legs, feet, or genitals, affecting groin or thigh nodes. Additionally, infections in the armpits can cause swelling in axillary lymph nodes.

Symptoms of swollen neck lymph nodes typically include tenderness, pain, and noticeable enlargement, resembling peas or beans. Respiratory infections can cause throat soreness, fever, and runny nose, often accompanying swollen glands. Night sweats may indicate serious conditions like tumors or immune disorders, highlighting the importance of medical evaluation. Whether mild or severe, persistent or chronic, symptoms should prompt consultation with a healthcare professional to determine the underlying cause and receive appropriate treatment.
