Why Do I Have a Lump Behind My Ear?
Lumps behind the ear are typically swollen lymph nodes responding to infections or irritation in the head and neck region. The most common causes include ear infections, upper respiratory infections, skin conditions like acne or eczema, and dental problems. Lymph nodes filter bacteria and viruses, becoming enlarged when fighting infection. Other potential causes include cysts, which are fluid-filled sacs, or in rare cases, more serious conditions. Most lumps are benign and resolve within 2-3 weeks as underlying infections clear. However, lumps that persist longer than 3 weeks, feel hard or fixed, or are accompanied by unexplained weight loss or night sweats warrant medical evaluation to rule out more serious conditions.
