Finding a lump or swollen node on your neck, back, or near your ear can be alarming, but most of the time, swollen lymph nodes are benign. They can enlarge due to infections, inflammation, or more serious conditions. This article explores the causes, symptoms, and management of swollen lymph nodes.
Lymph nodes are small, bean-shaped structures in your body that filter harmful substances. They swell in response to infections like the flu or strep throat, or conditions like ear infections, injuries, or allergies. In rare cases, swollen lymph nodes can signal lymphoma or metastatic cancer.
Seek medical attention if the swelling lasts more than 2-3 weeks, the lumps are hard and immovable, or if you experience unexplained weight loss, fever, or fatigue. For mild infections, warm compresses, over-the-counter pain relievers, and rest can help manage symptoms.
