Lymph nodes can be painful, especially when swollen. This pain, often described as tenderness, is usually a sign that your body is fighting off an infection. The soreness typically subsides within a few days as the infection clears. However, not all swollen lymph nodes are painful; sometimes they swell without causing any discomfort.
Understanding Lymph Node Pain
Swollen lymph nodes are a common response to infections, such as bacterial or viral illnesses like the common cold or tonsillitis. The body's immune system works to combat these infections, and enlarged lymph nodes are part of this process. This increased activity frequently leads to tenderness and pain in the affected nodes.
- Location Matters: Lymph nodes often swell in areas such as the neck, armpits, and groin. Pain is often localized to these regions.
- Infection Indication: Painful lymph nodes are generally indicative of an infection, although other factors can also cause swelling.
- Duration: Pain associated with infection-related swelling typically resolves once the infection is treated or subsides.
When to Seek Medical Attention
While pain in swollen lymph nodes often indicates a minor infection, it's crucial to consult a healthcare professional if:
- The pain is severe or persistent.
- The lymph nodes are significantly enlarged (over ½ inch wide).
- You experience other symptoms such as fever, weight loss, or night sweats.
- Swelling persists for more than a few weeks.
These symptoms could signify a more serious underlying condition. The Mayo Clinic notes that rarely, swollen lymph nodes can be caused by cancer.
