A normal lymph node that's reacting to just an infection is small, it's well-defined and a little rubbery, and usually moves. The lymph nodes that you got to worry about, however ,are going to be the ones that are matted, that are large, more than say maybe a half-inch around and they don't move very well.
Is it normal for lymph nodes to move?
A soft, tender and moveable lymph node usually indicates that it's fighting infection (not surprising at this time of the year). Nodes containing a spread of cancer are usually hard, painless and don't move. Nodes are found in many different parts of the body & any of them can swell if dealing with an infection.
Do lymph node lumps move?
Healthy lymph nodes are more rubbery than the surrounding tissue but are not solid like stone. Any lumps on the neck, groin or armpits that are hard, very enlarged, and do not move when pushed may indicate lymphoma or another type of cancer and should be investigated by your GP.
