My one yr old little girl has a small pea sized hard bump under the skin. there is no irritation with it just a bump. just makes me nervous. any ideas?

Consider consult.: The quickest and most accurate way to get a diagnosis is to bring your daughter into your pediatrician. There are far to many choices of what this can be based on your description.

Normal lymph node: We have lymph nodes scattered throughout our body & they are often detected in the neck where they sit on top of neck muscles. These nodes are little fluid strainers that take body lymph & remove stray germs from things like bug bites. They are often pea sized at rest & grow to dime sized when working. Within 2-3 wks they often shrink back down unless they are stimulated further.Ask her doc if so.
