4. Swollen Glands in the Neck or Groin: The Silent Indicators
Another symptom not directly visible on the face but highly indicative of cold sores is the swelling of glands. Lymph nodes, primarily located in the neck and groin areas, act as the body’s filtration system, trapping viruses and bacteria. When they detect the herpes simplex virus, they might swell in response.
Children might not notice this symptom immediately. The swelling, while significant, may not be overtly painful. However, upon touch, these swollen glands can feel tender or even slightly hard, resembling tiny peas beneath the skin.
But what’s the science behind this? Lymph nodes are like the body’s surveillance centers. When they encounter harmful pathogens, they produce more white blood cells to counter the invaders. This increase in activity causes them to swell, signaling that the body is actively fighting an infection.
Hence, while the face displays the cold sore’s visible symptoms, the neck and groin areas provide insights into the body’s internal defense mechanisms at play. (4)
