How do i treat swollen lymph nodes. jaw area, right below the ears.

Find the cause!: The most important thing is to figure out WHY you have enlarged lymph nodes...is there an infection somewhere? A dental problem? Something more serious? If it's been just a week or two and they're not enlarging with time, you're probably ok to watch them for a while. But if they persist beyond a month, grow, or are hard or fixed, you should be seen sooner than later to discuss next steps.
