See md: See doctor. For exam. See ENT if neck mass, lymph node etc lasting more than 3-4 weeks.

Normal lymph node: We have lymph nodes scattered throughout our body ; many 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.
