Reactive lymph node: The lymph nodes are located all over the body & sift body serum & remove various particles, germs & debris. After a viral infection it is common for local glands(that may be the size of a pea at rest)to swell to the size of an almond or larger if they are working to clear debris.They can become infected and need antibiotics to assist in healing.See your doc for confirmation.
