Hi my daughter is 14 and she has 2 lumps behind her ear about the size of a dime and it hurts when you touch it. what could it be?

Nodes: have your primary care evaluate it it could be just swollen lymph nodes and can be treated with antibiotics

Reactive Lymph nodes: Has she been sick recently? The most common "lumps behind the ears" are lymph nodes that are reacting to a recent or current infection, generally a "head cold", ear or sinus infection. The lymph nodes are part of the immune system and get rev'ed up a bit. They generally will decrease in size and become less tender after the inciting infection resolves.

Lumps: This could be a number of things including boils as well as swollen lymph nodes. You should take your daughter to a pediatrician and get this evaluated.

Tenderness infectio?: The pain associated with touching the area may indicate an infection. Please discuss a course of antibiotics with your physician. Monitor temperature, provide fluids and check other areas such the neck,under the arms for swelling.
